Notes
--------------------------------------------------------
I've tried switching different options for highlight_*() functions and crash still
occurs. Only __METHOD__ and __FUNCTION__ seem to crash it for me. I tested this same
thing on my live server which runs Apache 1.3.x, PHP 5.0.4 and Linux, but it does 
not crash. Only my local development server seems to be crashing from it. If you 
request will post php.ini settings too. Thanks.

Provide only the changes you've made to php.ini (compared to whatever you used as base).
