As written in pcre.c ... /*************************************************************************** **************************************************************************** RECURSION IN THE match() FUNCTION The match() function is highly recursive. Some regular expressions can cause it to recurse thousands of times. I was writing for Unix, so I just let it call itself recursively. This uses the stack for saving everything that has to be saved for a recursive call. On Unix, the stack can be large, and this works fine. It turns out that on non-Unix systems there are problems with programs that use a lot of stack. (This despite the fact that every last chip has oodles of memory these days, and techniques for extending the stack have been known for decades.) So.... There is a fudge, triggered by defining NO_RECURSE, which avoids recursive calls by keeping local variables that need to be preserved in blocks of memory obtained from malloc instead instead of on the stack. Macros are used to achieve this so that the actual code doesn't look very different to what it always used to. **************************************************************************** ***************************************************************************/ Thus NO_RECURSE should be set in win32 compiler oprions. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28317&edit=1
