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.

To be shown vulnerability began similar more often in 1.4.12 that guys from
Digitum have made many changes, concerning detours of deadlocks.
If my assumption is true, will have to alter this module (<lock.h>).
I had to disconnect there the doubtful debugging code supervising entring
in critical sections, together with one watchdog.
callguy -
I wait for results. If I have appeared the rights - I shall correct. Guys
from Digium are similar very borrowed even for discussion of this important
question. My E-mail to Russell Bryant has remained without the answer.
