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.
