I'm getting a problem with gcc building Phalcon successfully:

==> default: /bin/bash /tmp/cphalcon.z23OXJ/build/64bits/libtool --mode=compile gcc  -I. -I/tmp/cphalcon.z23OXJ/build/64bits -DPHP_ATOM_INC -I/tmp/cphalcon.z23OXJ/build/64bits/include -I/tmp/cphalcon.z23OXJ/build/64bits/main -I/tmp/cphalcon.z23OXJ/build/64bits -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib  -DPHALCON_RELEASE -DHAVE_CONFIG_H  -march=native -mtune=native -O2 -finline-functions -fomit-frame-pointer -fvisibility=hidden   -c /tmp/cphalcon.z23OXJ/build/64bits/phalcon.c -o phalcon.lo

To confirm the build of the library failed, I double checked the loaded modules:

$ php -m | grep phalcon
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/phalcon.so' - /usr/lib/php5/20121212/phalcon.so: cannot open shared object file: No such file or directory in Unknown on line 0

Have you run across this before?

@slogsdon yes problem gcc48/gcc49 more memory usage... 512mb gcc overrflow

[slogsdon]

Is there a way to get around the overflow issue? If not, would the default gcc suffice, or does the issue affect that as well?

[denji]

@slogsdon fixed https://gist.github.com/denji/7f517e8cb8fd1ff0ad8c

1. -fno-delete-null-pointer-checks regression gcc4.8/4.9
2. -fno-builtin-memcmp regression gcc4.8/4.9
3. -pie -fPIC -Wl,-z,relro,-z,now -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2, RedHat uses them by default, they remove memory leaks and security issues, factor productivity dropping 1%
4. -ftrack-macro-expansion=0 regression gcc4.8/4.9
