From: dziastinux at gmail dot com Operating system: Windows 7, CentOS 5.4 PHP version: 5.3.1 PHP Bug Type: Reproducible crash Bug description: garbage collector crash
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 ...
