Segmentation fault (core dumped) in PHP7

[raybogman]

There is a PHP7-CLI bug when running the install via the shell

Segmentation fault (core dumped)

I tested it in CE and EE 2.0

when switching to PHP5.6-CLI everthing works. It's only during installation, no other issue in PHP7 so far

[alankent]

Hi Ray! Which version of PHP7 did you use? 7.0.0 or 7.0.1? Also, exactly what command did you run? (I run the install from PHP 7.0.1 without problem.)

[raybogman]

Alan its PHP 7.0.1

deb http://ppa.launchpad.net/ondrej/php-7.0/ubuntu trusty main deb-src http://ppa.launchpad.net/ondrej/php-7.0/ubuntu trusty main

[alankent]

What exactly was the command you ran? (All the command line arguments too.) Just trying to repeat your problem.

[raybogman]

php bin/magento setup:install --db-host=localhost --db-name=magento2ce --db-user="root" --db-password="root" --backend-frontname=admin --base-url=http://yourdomain.com/ --admin-lastname=Doe --admin-firstname=John --admin-email=john@doe.com --admin-user=admin --admin-password=password123 --use-rewrites=1 --cleanup-database

[alankent]

Thanks Ray. I tried your command with PHP 7.0.1 and got the following.

$ php bin/magento setup:install --db-host=localhost --db-name=magento2ce --db-user="root" --db-password="root" --backend-frontname=admin --base-url=http://yourdomain.com/ --admin-lastname=Doe --admin-firstname=John --admin-email=john@doe.com --admin-user=admin --admin-password=password123 --use-rewrites=1 --cleanup-database

I tried fiddling the settings (change DB name, changing passwords etc). No change. (The error message here is not very helpful to say what exactly is wrong.) Here is the command I successfully used in a script with PHP 7.0.1 in case useful

bin/magento setup:install --backend-frontname=admin \
    --cleanup-database --db-host=127.0.0.1 --db-name=magento --db-user=magento --db-password=magento \

    --admin-user=admin --admin-password=admin123 --language=en_US \
    --currency=USD --timezone=America/Chicago --use-rewrites=1 --use-sample-data

The head of my php -i output is as follows:

I have to go get some other work done, so I am going to leave this to the Engineering team to chase down. Just sharing where I got up to. I am almost wondering if copy/paste is sneaking some unicode hyphen in somewhere...

Ahhh... I just changed "localhost" to "127.0.0.1" and it started working I think. I remember reading something about MySQL treats "localhost" as a special string, not as a host name. So it might be something to do with the MySQL libraries causing you a problem, not PHP 7 itself. My Docker image is not doing a 'standard' thing to get MySQL installed.

[marvincaspar]

Are you using Xdebug with PHP7? If yes, try to disable Xdebug and run the command again.

[raybogman]

@mc388 no Xdebug installed only required php modules

[monkeysee]

Created internal ticket MAGETWO-47636 for investigation

[mazhalai]

@raybogman can you please add the following to your php.ini, restart server and try installing again. Please post contents of path_to_log_file.

log_errors = On
error_log = <path_to_log_file>

[keithbentrup]

I had a seg fault during the cli install due to a memory allocation issue using the php7 package from ppa:ondrej/php. However, I had previously been using php7-beta1 from http://repos.zend.com/zend-server/early-access/php7/repos just fine. I haven't had time to investigate further so I reverted to php7-beta1 from zend.

My environments can be replicated using these Dockerfiles based on an ubuntu 14.04 image: working - https://github.com/esepublic/docker-lamp-app-server/blob/0985a6fe7cfa2799593b418a97197ef839f198a7/Dockerfile seg faults - https://github.com/esepublic/docker-lamp-app-server/blob/a0724e9a7ce93d036c22eb32243686ffa6d8e937/Dockerfile

[mazhalai]

@keithbentrup why are you using php5 extensions for gd and mcrypt etc? ETA: Sorry I saw the working one first. But that is still inconsistent with some php7 mixed with php5.

These steps worked for me:

add-apt-repository -y ppa:ondrej/php-7.0

apt-get update

apt-get install -y apache2 libapache2-mod-php7.0 php7.0  php7.0-common php7.0-gd php7.0-mysql php7.0-mcrypt php7.0-curl php7.0-intl 

[raybogman]

new PHP 7.0.2 is out

it looks like there is a core bug https://bugs.php.net/bug.php?id=71163

I am going to test it

[csdougliss]

With PHP 7.0.2 I still get the following when reindexing catalogsearch_fulltext

Segmentation fault: 11

I can't use PHP 7 and I can't use HHVM, not a good start!

[acidreian666]

@craigcarnell I get the same exact problem on php 7.0.2 on reindexing catalogsearch_fulltext Link to my Magento Stack-exchange with pictures http://magento.stackexchange.com/questions/96590/magento-2-0-with-upgraded-to-php-7-0-indexer-stuck-at-processing

[keithbentrup]

@mazhalai re the php5 exts with php7-beta ... at the time, the php7-beta didn't have all the extensions and the php5 ones were compatible

Regardless, I set up a docker image were you can reproduce the problem.

docker run -it esepublic/m2-php7-install-test (more info here: https://github.com/esepublic/docker-m2-php7-install-test)

It appears to be due to a memory allocation error (it consume all available memory) when it calls prepareProductIndex in Magento/CatalogSearch/Model/Indexer/Fulltext/Action/Full.php.

[mazhalai]

@kiethbentrup yes we are aware of issues in indexer on PHP7(this is a duplicate of #2750), but this thread started as Segmentation fault for install. Do you still have problems installing Magento2 on PHP7?

@raybogman any update regarding installation using PHP7? We cannot reproduce the segfault during installation.

[keithbentrup]

@mazhalai yes, that's what i'm saying - the install fails with php7 and I've created a reproducible docker container here, so you can see for yourself:

docker run -it esepublic/m2-install-tests:php7-install-test

If you have docker, just run the 1 cmd, watch it all install and you'll see it fail during the install at the point that I described. Find the Dockerfile and install script (install-m2.sh) here: https://github.com/esepublic/docker-m2-install-tests/tree/php7-install-test

[keithbentrup]

[mazhalai]

@keithbentrup You have sample data, did you try installing without sample data?

[keithbentrup]

I'm only trying to install with sample data. I have no need for an installation without sample data at this time, but if that makes it a duplicate of #2750, then I guess it's not a separate issue.

[mazhalai]

@keithbentrup just tried with sample data, and got a segfault! It is related to indexer issue #2750.

[SunshineTech]

When I install Magento2 on CentOS7 with php7, the following error display:

[Progress: 317 / 362] Module 'Magento_CatalogSampleData': Installing data.. Segmentation fault

Hi there!

I'm experiencing this problem as well since I switched from the PHP7 version I built from source to the package provided Ondřej Surý for Ubuntu (ondrej/php-7.0).

I used to compile PHP7 with the following options:

--prefix=/usr/local --enable-soap --enable-bcmath --with-mcrypt --with-xsl --enable-mbstring --with-curl --with-gd --with-jpeg-dir --with-png-dir --enable-intl --enable-fpm --with-openssl --with-pdo-mysql --with-mysql-sock=/var/run/mysqld/mysqld.sock --enable-zip --with-zlib --with-zlib-dir

ondrej/php-7.0 was built with the following options:

--includedir=/usr/include --mandir=/usr/share/man --infodir=/usr/share/info --libdir=/usr/lib/x86_64-linux-gnu --libexecdir=/usr/lib/x86_64-linux-gnu --disable-maintainer-mode --disable-dependency-tracking --prefix=/usr --enable-cli --disable-cgi --with-config-file-path=/etc/php/7.0/cli --with-config-file-scan-dir=/etc/php/7.0/cli/conf.d --build=x86_64-linux-gnu --host=x86_64-linux-gnu --libdir=/usr/lib/php --libexecdir=/usr/lib/php --datadir=/usr/share/php/7.0 --program-suffix=7.0 --sysconfdir=/etc --localstatedir=/var --mandir=/usr/share/man --disable-all --disable-debug --disable-rpath --disable-static --with-pic --with-layout=GNU --without-pear --enable-bcmath --enable-calendar --enable-ctype --enable-dba --with-db4=/usr --without-gdbm --with-qdbm=/usr --enable-inifile --enable-flatfile --enable-dom --enable-exif --with-gettext=/usr --enable-fileinfo --enable-filter --enable-ftp --enable-hash --with-iconv --with-pcre-regex=/usr --enable-mbregex --enable-mbregex-backtrack --enable-mbstring --enable-phar --enable-posix --enable-mysqlnd-compression-support --with-zlib-dir=/usr --with-openssl=yes --enable-libxml --enable-session --enable-simplexml --enable-soap --enable-sockets --enable-tokenizer --enable-xml --enable-xmlreader --enable-xmlwriter --with-mhash=yes --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-zip --with-system-tzdata --enable-dtrace --enable-pdo --enable-mysqlnd --enable-pcntl --with-libedit=shared,/usr build_alias=x86_64-linux-gnu host_alias=x86_64-linux-gnu CFLAGS=-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -O2 -Wall -fsigned-char -fno-strict-aliasing -g LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro CPPFLAGS=-D_FORTIFY_SOURCE=2 CXXFLAGS=-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security

[ishakhsuvarov]

@cedricblondeau

while (0 > 1) {
}

Evaluates to false, so the loop never starts and causes catalogsearch_fulltext index to be empty.

[cedricblondeau]

@ishakhsuvarov My bad!

[mazhalai]

@all PHP7 issues have been fixed in tag 2.0.1 Please have a look and let us know if your issue has been fixed.

[csdougliss]

@mazhalai Well done :+1:

[mazhalai]

Closing this issue, please reopen if it persists.

[josefbehr]

I still get a Segmentation fault with Magento 2.0.1 on PHP7.0.0, when running the setup:di:compile command:

Not sure, if this is a PHP or Magento problem...

[danslo]

Upgrade your PHP version, I believe this was fixed in 7.0.3 or even 7.0.4.

[stefandoorn]

I also have this problem on PHP 7.0.4. Magento 2.0.2. It also fails on the first 14% somewhere. See referenced issue above. If I take out that library, it continues beyond the 14%.

[Ravenmire]

I get this segfault when installing from git.

The last lines in the compile are: Installing PEAR environment: /usr/local/lib/php/ Makefile:455: recipe for target 'install-pear-installer' failed make[1]: *\ [install-pear-installer] Segmentation fault (core dumped) Makefile:458: recipe for target 'install-pear' failed

What further is needed to diagnose and fix this problem?

[gusterwoei]

I was using php 7.1.0-alpha and got the same issue, then I upgraded to 7.1.0-beta it started working fine. It's really the php problem

[sma09sjb]

I'm experiencing a similar issue on php version 7.0.8 with a CE installation of Magento 2.1

Can anyone offer any help? This is preventing me from setting the mode to production on our server.

Thanks,
