Edit report at https://bugs.php.net/bug.php?id=47689&edit=1 ID: 47689 Comment by: djokodonev at gmail dot com Reported by:vr...@php.net Summary:crash with certain regular expression Status: Not a bug Type: Bug Package:PCRE related Operating System: win32 only PHP Version:5.*, 6CVS (2009-03-17) Assigned To:pajoye Block user comment: N Private report: N New Comment: This should be added to the PCRE(preg_match etc..) documentation. It had me clules for a long time as of what it going on. Previous Comments: [2011-09-29 13:34:44] paj...@php.net It would be nice to add that to both apache 2.2 configuration and pcre docs. [2011-09-29 12:35:55] ferenczy at volny dot cz Better way to alter Apache stack size is using the ThreadStackSize directive in the Apache's configuration file (httpd.conf). There is a description of the ThreadStackSize directive in Apache's documentation: http://httpd.apache.org/docs/2.2/mod/mpm_common.html#ThreadStackSize So increase of Apache stack size might looks like this (lines from httpd.conf): ThreadStackSize 8*1024*1024 It sets Apache stack size to 8 MB, so it's the same as a default value on Linux. [2009-07-06 17:43:44] paj...@php.net That's not something we can change for apache. You can fix the problem by increasing the stack size for apache using the following command: editbin /STACK:800 c:\apache22\bin\httpd.exe Sadly this tool is not available as a standalone app but VC Express should have it. Close (bogus) this bug as it is not something we can change in PHP. We can increase the stack at wish but it is apache dependent. FastCGI does not seem to have this problem (was not able to crash it).
