Edit report at https://bugs.php.net/bug.php?id=63349&edit=1 ID: 63349 Updated by: sixd@php.net Reported by: phpwnd at gmail dot com Summary: Segfault during GC -Status: Open +Status: Feedback Type: Bug Package: Reproducible crash Operating System: Gentoo Linux PHP Version: 5.4.8 Block user comment: N Private report: N New Comment: Thanks for the report. Can you continue working on it and: - Upload a script that reproduces the problem when XDebug is not installed - Upload build & configuration information - Try with zend.enable_gc = Off Previous Comments: ------------------------------------------------------------------------ [2012-10-24 20:48:11] phpwnd at gmail dot com Description: ------------ PHP 5.4.8 + XDebug 2.2.1, no other extensions I've been experiencing a few segfaults lately. They've been a bit hard to reproduce because so far I've only hit them when using PHP_CodeCoverage and only on specific revisions of my code (adding or removing a single statement such as "$a=1;" would keep it from happening.) I have gotten around rebuilding PHP with all the debug bells and whistles and the resulting backtrace (hopefully attached to this bug) indicates it's related to GC and/or PCRE. Adding a call to gc_collect_cycles() fixed it for me, at least for now. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63349&edit=1
