Bug #16360 Updated: Segmentation fault in Array functions

ID: 16360 Updated by: max@home-werner.de Reported By: nohn@php.net Status: Open Bug Type: Reproducible crash Operating System: Linux, Windows PHP Version: 4.0CVS-2002-03-30 New Comment: I did the same test on my machine (Linux 2.4.18, PHP 4.1.2 CGI-Version). My php.ini looks like this: memory_limit = 8M log_errors = On error_log = syslog When I run the test routine nothing appears in my syslog and I get the segfault.

If the user enables following options in php.ini ([PHP]-section), --- log_errors = On error_log = syslog --- PHP first shows an memory-limit error, after that Apache/PHP dies with an segmentation fault. If "error_log" is set to "/some/file", PHP is unable to log anything. The only logging facility that logs the segmentation fault is syslog. Demonstration: <?php $theline = "hello, i'm the line"; for ($i = 0; $i < 1000000; $i++) $testarr[$i] = $theline; ?> Following script does'nt cause a segmentation fault: <?php for ($i = 0; $i < 1000000; $i++) $testarr[$i] = "hello, i'm the line"; ?> So far we could test following Versions: PHP Webserver OS console (sf/ml) apachemod (sf/ml) 4.0.1 - Linux ?
