From: phajdan dot jr at gmail dot com Operating system: Linux (Gentoo 2007.0) PHP version: 5.2.5 PHP Bug Type: Scripting Engine problem Bug description: crashes in _zend_mm_free_int
Description: ------------ I have a not-so-small script (20k LOC) and there is a problem during some extensive operations in it: a crash. I tried to find out which part of my program could cause it (tried to comment out some fragments of code etc - but the code isn't very simple, so I couldn't find a fragment possibly related to the crash). I have 3 backtraces, with PHP compiled with -debug (Gentoo USE flag). When compiled with debug, the issue doesn't persist. I don't know how should I debug the problem - if I can do something to help you fix it - I will. Actual result: -------------- Backtrace 1: #0 0xb7782fe8 in _zend_mm_free_int () from /usr/lib/apache2/modules/libphp5.so #1 0xb77a6d46 in zend_hash_destroy () from /usr/lib/apache2/modules/libphp5.so
