Description:
------------
I am using APC 3.0.8 and it segfaults apache from time to     
time (i don't know what triggers it). I am using Apache   
2.0.55 with mpm-prefork. 

Actual result:
--------------
GDB backtrace:

Not much I can do with this report.  I'd need way more details.  First, try using the current CVS version and then try to narrow down exactly which scripts might be causing this.
