Summary:                    app_dial segfaults asterisk while trying to bridge
channels
Description: 
app_dial causes a seg fault while trying to bridge channels on system
placing many calls. 

I was running Vicidial (a predictive dialer) on this server with twenty
agents and dialing at a ratio of four to one. This means that there are
twenty channels waiting in twenty meetmes and the server is dialing 80
numbers via IAX to another XEN server on the same box. When a number
connects they get placed into one of the meetmes.

This crash happened amongst some other crashes that I am still debugging.
I have not been able to narrow down exactly what caused this one. Most
likely a threading issue.

What version/build of glibc do you have? 
I did notice an entry about a "fix pthread_mutex_timedlock() on x86_64" on
my system and am currently checking that out..
