The backtrace doesn't tell me much at first glance.  I'm quite certain
it's not hung in memcpy since I'm highly confident memcpy doesn't
have an undiscovered bugs. :)  Instead it's presumably looping in
receive_packet or at a higher level, possibaly in dispatch.  At the very
least I need a coredump and your executable so I can look at variables
in receive_packet.

Thanks for your report.
