It may not use the 16MB but most of apache builds out there use a way too small stack size on windows. Much smaller than on Linux. ------------------------------------------------------------------------ [2013-01-07 20:08:03] remi at minimal-beton dot com 16 Mo to manage a 160 length string... I'm not enough good to understand :( ------------------------------------------------------------------------ [2013-01-07 19:17:06] ab@php.net After editbin /stack:16777216 httpd.exe I get bool(false) while running under apache. Previously crash with the default value. Seems like it can be solved with just increasing the stack size ------------------------------------------------------------------------ [2013-01-07 18:38:34] pajoye@php.net Can you try in CLI please? While you did not provide a backtrace, I am pretty sure it is related to PCRE stack limit issue. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
