Summary:                    SIP hairpin invokes Local within app_dial to produce
a crash.
Description: 
We are getting crashes in app_voicemail on a fairly regular basis.  I'm
still working on steps to re-produce, but I thought I would post the
backtraces here in case someone could glean anything from them.  I will
update if I can figure out the steps to re-produce.

Corydon76, qwell-

We did get another crash that looks very similar but is not exactly the
same to the ones we originally reported here.  This is on one of the
upgraded servers that is running 1.4.11 with Corydon76's local channel
de-optimization patch.  This crash points to chan_sip, but it definitely
seems related.  This is the last line of the messages file:

[Sep 19 09:17:29] ERROR[15843]
/usr/src/asterisk-test/1.4.11/asterisk-1.4.11/include/asterisk/lock.h:
chan_sip.c line 15175 (sipsock
_read): mutex '&p->owner->lock' freed more times than we've locked!

What was happening at the time of the crash is a call being delivered to a
large ring group with 32 sip peers being dialed with
Dial(SIP/PEER1&SIP/PEER2...).

I've also uploaded a new bt/btfull from this core file.
