Archlinux + PHP 5.4.7 ------------------------------------------------------------------------ [2012-09-17 09:59:00] pierre at archlinux dot de It also crashes with the imap extension disabled. But it seems the number of enabled extensions might matter. Anyway, we have a backtrace and the commit that introduced this issue. ------------------------------------------------------------------------ [2012-09-17 09:55:04] daniel at bashgeek dot net Have the same problem on my end with a couple of servers. For me the problem is solved as soon as I disable the IMAP extension of PHP. Maybe it has something todo with this extension? ------------------------------------------------------------------------ [2012-09-12 16:32:02] jeffrey dot ness at rackspace dot com I am also noticing this issue with our 5.3.16 packages: # php-fpm -v PHP 5.3.16 (fpm-fcgi) (built: Aug 20 2012 10:39:20) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies # for i in {1..100}; do php-fpm ; killall php-fpm; done Segmentation fault Segmentation fault Segmentation fault # dmesg | grep php-fpm php-fpm[30800]: segfault at 7f7d199f4cd0 ip 00007f7d24a43b83 sp 00007fffdd48fb20 error 4 in ld- 2.12.so[7f7d24a35000+20000] php-fpm[31599]: segfault at 7f50f17c3cd0 ip 00007f50fc812b83 sp 00007fff09f13120 error 4 in ld- 2.12.so[7f50fc804000+20000] php-fpm[32009]: segfault at 7f3005f59cc0 ip 00007f3010938b83 sp 00007fffb291c3a0 error 4 in ld- 2.12.so[7f301092a000+20000] php-fpm[32313]: segfault at 7f17094a4cc0 ip 00007f1713e83b83 sp 00007fffaab94e20 error 4 in ld- 2.12.so[7f1713e75000+20000] php-fpm[32585]: segfault at 7f60ad427cc0 ip 00007f60b7e06b83 sp 00007ffff44e06a0 error 4 in ld- 2.12.so[7f60b7df8000+20000] ------------------------------------------------------------------------ [2012-08-24 09:06:27] pierre at archlinux dot de I have attached php.ini and php-fpm.conf as patches (sorry, didn't fint another way to attach those) Here is what is different from the configuration shipped with PHP 5.4.6: The php-fpm.conf is the plain upstream one with this patch applied: https://projects.archlinux.de/svntogit/packages.git/tree/trunk/php-fpm.conf.in.patch?h=packages/php php.ini is a copy of php.ini-production with this patch applied: https://projects.archlinux.de/svntogit/packages.git/tree/trunk/php.ini.patch?h=packages/php On top of that I applied the following changes locally: http://paste.xinu.at/Hp6/ ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
