ID: 51069 Updated by: pajoye@php.net Reported By: dziastinux at gmail dot com -Status: Open +Status: Feedback Bug Type: Reproducible crash Operating System: Windows 7, CentOS 5.4 PHP Version: 5.3.1 New Comment: Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2010-02-17 15:17:40] dziastinux at gmail dot com Description: ------------ PHP crashes in the middle of the script with no error in any logs (php, apache(thread-safe), cherokee(fcgi)). The sad thing is that I can't provide a sample code to reproduce the problem. The crash occurs on script with huge arrays filled with objects. A lot of references exists between objects and arrays. (Memory usage ~200mb). Actual result: -------------- php5ts!zval_mark_grey+4 0330d0f0 01af39f8 035c9eb8 ...
