********DISCLAIMER******************* I AM NOT A C/C++ PROGRAMER!!!!!!!!!!! *************************************

I am working on a patch to autocreate maildirs. When I run maildrop, the maildirs are created, but I get a signal 0x0B. I am told that this means that there is an invalid pointer being referenced. How do I figure out what is causing it?

Thanks, Rob
