#31648 [Opn->Bgs]: php -r Segfault when assigning values in an array in an infinite loop.

ID: 31648 Updated by: derick@php.net Reported By: kermodebear at kermodebear dot org -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Redhat Linux krnl 2.4.21-20ELsmp PHP Version: 4.3.10 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Arrays have a limited size... you're definitely exceeding this with this code. Previous Comments: ------------------------------------------------------------------------ [2005-01-21 22:16:24] kermodebear at kermodebear dot org 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.
