Unfortunately just having USE=debug isn't all that you need.  I use a bash
alias like so:

alias debug="USE=debug FEATURES=nostrip CFLAGS=-ggdb3 CXXFLAGS=-ggdb3"

then you can just run 'debug emerge blah'.

You'll probably want to rebuilt apache2,apr,apr-util,mod_perl and possibly more
depending on what exactly you're looking for.

Finally, to get it to dump core, you'll probably have to add 'ulimit -c
unlimited' to your apache2 init script.

Hi Aaron,

I did all of this but a couple of segfaults don't seem to have
generated any "core" files.  Do you know where they should be located
and what they should be called?  Is there anything else I need to do
to get those files to dump?
