Debugging mod_perl

[Nico Erfurth <ni...@headlight.de>]

Hi,


i'm creating an accounting system for my employer, the webfrontend is 
created with mod_perl.

Today i had a big problem, and i don't know how to track it down.
After changing one of my tool-modules apache segfaults on startup.

So, how can i debug something like this?
Are there any hooks inside of mod_perl i could use?
Do i need to debug apache itself?

Where could i start such debugging?

Do you know exactly what you changed?  In that case, you have a small 
amount of code to look through for the problem.  Take stuff out until it 
stops segfaulting.  If you want some help figuring out why that part 
segfaults when you find it, post it here.

Try to 
use:http://perl.apache.org/guide/debug.html#Using_the_Interactive_Debugger
If you cannot figure out how to do it yourself read the SUPPORT file in 
the mod_perl distribution and follow the instructions on how to send the 
gdb backtrace to the list.
