kowalma: When Asterisk was crashing before, was it happening while someone
was using ChanSpy but not actually spying on anyone? Russell and I solved a
stack overflow in the code yesterday that would show itself when attempting
to spy using the 'g' option to ChanSpy. If there were no channels in the
spygroup specified, then the spyer would continuously loop. With each loop,
a small bit of stack space would be allocated using an ast_strdupa call
until eventually there was an overflow.

I noticed that you were using the 'g' option for ChanSpy and it made me
think that this might be the same issue.
