segmentation fault in php-fpm #39

Open stavrak opened 3 years ago

stavrak commented 3 years ago

Issue: When i add the extension into the php.ini, php-fpm is not starting anymore returning segmentation fault.

Background: After seting the env variable for the pkg config (necessary for me to compile dlib, see https://discuss.getsol.us/d/5423-compiled-library-not-found/2) and installing lang/gcc before running ./configure (otherwise i got a library lstdc++ not found during make) i finally got it compiled. But if i add it to the php.ini the php-fpm service fails with segmentation fault.

System: Nextcloud plugin (12.1-RELEASE-p10) running on trueNas (TrueNAS-12.0-RELEASE) as jail (container). php version: 7.4.12

OliverPA77 commented 3 years ago

I have the same issue on TrueNAS-12.0-U1 and PHP 7.4.13, ie. seg fault when starting php. Tried as well in a separate jail without php-fpm - same result. Frustratingly even with all logging enabled in php.ini there isn't a trace of a log anywhere.

edit: Does it choke on reading a locale file?

hm, I'm stuck at the same point. I will try on a vanilla freebsd system to see if this is related to FreeNAS

Hi, Is there any update on this? I encountered the same problem..

Thanks Jail version: 12.2-RELEASE-p6 image

ethnh commented 2 years ago

Hello, I am having the same issue on a vanilla FreeBSD system ( FreeBSD 13.0-RELEASE-p4 ) Are there any fixes?

Performing sanity check on php-fpm configuration: Segmentation fault

no way of getting pdlib running on freebsd with php8

jasonhensler commented 2 years ago

Clean build on freebsd 13.1 with php8.0.19, dlib install from ports or from okg still showing segmentation fault for php-fpm.

qudiqudi commented 1 year ago

Still seg faults when building on freebsd. It's building fine but starting php-fpm with the extension seg faults. Using pkg dlib-cpp-19.22, php80

make test results in *** Error code 139

I just ran into this issue today as well on TrueNAS-13.0-U2. Hoping there might be a fix sometime so I can get FaceRecognition installed.

brennoflavio commented 1 year ago

Could reproduce this error in freebsd with php 7.4 too
