RE: SIGSEGV Errors

[decker]

Thanks for the aid so far.

I've followed the debug process that Adam outlines, and the following is
returned from the bt command:

(gdb) Previous frame inner to this frame (corrupt stack?)

I apologise for my ignorance here.  Can anyone shed more light on what this
means?  I would assume so far that there is a problem with the memory
handling.  My suspicion is that empty memory is trying to be accessed, but
that's just an educated guess based on the sort of error it is.
