Description:
------------
[master][~/Projects/Test] /usr/local/php5/sbin/php-fpm -i | ack 'error_log'
error_log => /usr/local/php5/var/log/php_errors.log => 
/usr/local/php5/var/log/php_errors.log
php-fpm(30748) malloc: *** error for object 0x10122b890: pointer being freed was 
not allocated
*** set a breakpoint in malloc_error_break to debug
zsh: abort      /usr/local/php5/sbin/php-fpm -i | 
zsh: done       ack 'error_log'

This also happens when using the built in server and when using the apache module 
when APC is enabled.

[APC]
apc.enabled = off

and the issue stops. php-osx.liip.ch is where the php version is installed from.

Hi

I also experience this issue on Linux Ubuntu Server 8.04 LTS

[2011-12-16 17:55 UTC] lolautruche at gmail dot com

no more segfault with latest php 5.4 build and APC built from trunk

[2011-12-17 11:10 UTC] henrik at bjrnskov dot dk

Where is apc svn ?

[2011-12-17 11:14 UTC] lolautruche at gmail dot com

Here : http://svn.php.net/repository/pecl/apc/

[2011-12-28 15:50 UTC] henrik at bjrnskov dot dk

Just tried compiling a 5.4RC4 manually and installing apc from svn and pecl.

both php-fpm and apache2 module segfaults.

OS X Lion 10.7.3

[2012-01-12 20:04 UTC] josh at joshbutts dot com

Happens also in 5.4RC5 with APC from pecl on OSX 10.7.3

[2012-03-08 06:28 UTC] un+phpbugs at rob dot mx

I can confirm the same issue on Mac OS X 10.7, APC 3.1.9 and PHP 5.4.0 . 
Installing from trunk helps, but the logging of the error persists.

[2012-03-10 17:51 UTC] nathan dot renniewaldock at gmail dot com

Same problem for me with PHP 5.4 and APC trunk (r324082)

Wtf dude, 3 months and no solution? do something about this, PHP 5.4 is utterly useless without APC.

[2012-05-01 22:07 UTC] jim at zomm dot com

Experiencing same issue with PHP 5.4.0 & Apache/2.2.22 on CentOS release 6.2.

-Package: FPM related +Package: APC

[2012-05-22 15:58 UTC] fat@php.net

this is not a bug in FPM but in APC.

If it's still reproduceable, please post a fresh BT. It would be useful to 
install debug symbols before.

This bug can be reproduced in php 5.4.7 having apc enabled. Disabling the apc 
extension does not produce the error.
Apc has been installed with 'pecl install apc'. The php version 5.3.17 with apc 
enabled does not have this issue.
Both versions have been compiled and testen on the same system: Linux 3.2.0-31-
generic-pae #50-Ubuntu SMP Fri Sep 7

Same issue - CentOS 6.3 x64, PHP 5.4.7, APC stable 3.1.9 (but same segfault 
using latest beta).
