OK I was able to figure this out.  I'll answer inline here:

Yes it should. :)

Turns out that (as far as I can tell) what was occuring is that I was
linking against a library that had some export symbols in it.  I was
creating a static executable.  Somehow this confused the heck out of
it.  Any thoughts as to whether the root "cause" of the problem is ld
or gdb? Hmm.
