You mean it is loading, not that it's working :)

Hmm, that's not particularly nice.. But it's not crashing inside perl  
- so I'd guess this is an issue with your apache and/or mod_perl,  
rather than with the perl code itself.

This would be as apache forks, and the gdb doesn't follow that..

How much of the config can you remove (and still get the segfault?)

Does it only take the PerlSwitches line and/or the <Perl> block (if so  
it's _definitely_ an issue with your mod_perl/Apache, as with the  
'PerlModule' statement removed, no code except mod_perl is actually  
being loaded.
