Re: [PHP-DEV] Apache gdb backtrace... Help?? From: Rasmus Lerdorf (rasmus <email protected>)
Date: 04/12/00

This backtrace doesn't touch any of the PHP code. It does hit mod_info
which I actually wrote, but that doesn't quite mean this is the right
place for the question.

Try disabling mod_info and try your test again.
