It crashed Apache? Yow! Does that mean that it's an Apache bug? I didn't
think that PHP was supposed to be able to do that.

My Apache 2.0 configuration isn't anything special; after I corrected a bug
in index.php, creating a wiki worked out of the box. I'm running Linux, though;
if your Apache setup is fairly normal, then I'd expect that this is a Windows-
specific problem. That's about all I can say, since I don't have access to
a Windows box running Apache 2.0.

Since php is loaded as shared module it is able to crash the parent 
process. It happens all the time on certain php bugs.
Sessions exceeding ~4000 bytes, certain hairy pcre pieces (fixed 
recently), recent 4.3.10 - old zendoptimizer incompatiblities, or just 
thread-unsafe php libs.

Esp. apache2 (in the threaded worker model, old-style prefork is okay) 
is problematic with thread-unsafe php libs. That's why Rasmus excplictly 
recommends NOT to use apache2 worker model in production enviroment, 
together with php.
"Do not use Apache 2.0.x and PHP in a production environment neither on 
Unix nor on Windows." --

I personally also found the php mime-type overrides with apache2 are 
broken, but there are workarounds.
