Please try using 5.3.0 VC9 snapshots(ts or NTS): http://windows.php.net Previous Comments: ------------------------------------------------------------------------ [2009-04-10 15:15:15] nlop...@php.net this is the usual stack problem. Since we now use the stack for PCRE recursion on Windows, I think we could increase the stack size. The default (1 MB) is a little short.. Pierre: can you please increase the stack size on windows binaries to e.g. 8 MB? It's a matter of adding one parameter to the compile arguments.

I've found out that with much longer input (600 lines) the script crashes also in CLI. There's no crash in PHP 5.2.8, only PHP 5.2.9 is affected. ------------------------------------------------------------------------ [2009-03-18 23:16:14] fel...@php.net Hi Jakub, please check the pcre.backtrack_limit and pcre.recursion_limit value. ------------------------------------------------------------------------ [2009-03-18 13:10:15] vr...@php.net I've uploaded the backtrace analysis to http://www.vrana.cz/phpbug47689.zip ------------------------------------------------------------------------ [2009-03-17 13:57:03] vr...@php.net Description: ------------ Apache 2.2.11 crashes with PHP 5.2.9-1 on the following code. The same script run from CLI executes without crash.
