Summary:                    Abort in free() in local_hangup, possibly related to
failure to provide ringback indication
Description: 
We tried running under valgrind, but that didn't produce any obvious
indications of problems, and also made the ring back indication problem go
away, suggesting that there may be a common race condition that is causing
both.

I ran SIP history on the outgoing call and got the expected
INVITE/Trying/Ringing sequence.

gdb was only able to see the one thread.  I don't know if that is because
it was an abort(), or because memory corruption has prevented it from
finding the information about the threads.

Unfortunately even labbing up those scenarios doesn't seem to cause my
chan_local to crash even under high load. While I investigate further it
would be useful to know whether this happens in 1.6.0.9 as well, there have
been some changes in chan_local specific to the hangup handling that may
change things.
