From: kermodebear at kermodebear dot org Operating system: Redhat Linux krnl 2.4.21-20ELsmp PHP version: 4.3.10 PHP Bug Type: Reproducible crash Bug description: php -r Segfault when assigning values in an array in an infinite loop.
Description: ------------ When using the -r option on the command line and the code below, PHP will cause a segmentation fault after script time limit is reached. This is reproducable in that it happens most of the time, but not all of the time. Once, PHP simply hung when the time limit was reached; I let it sit for about a minute after the 'time limit exceeded' message was displayed, and was able to kill it with ^C. System is running RedHat Linux Enterprise Edition, with kernel version 2.4.21-20.ELsmp.
