Summary:                    Segfault after Manager Bridge
Description: 
I have configured the dialplan like this:

exten => _X.,1,Ringing()
exten => _X.,2,Wait(1000)
exten => _X.,3,Goto(2)
exten => _X.,4,Answer()
exten => _X.,5,Goto(2)

When a call comes in the context, by AMI, I can redirect the created
channel to 4th priority for answer the call. 
When I receive a Channel State UP for this channel, always by AMI, I can
Originate an Async new Call and put it on the same context.
When I receive the Success Originate Response Event, finally make the
Bridge for the two channels obtained.

This goes very well almost every time, and the two channels are connected
between them.

If one of the channels, DURING THE EXECUTION OF THE BRIDGE, hangups,
asterisk crashes.

Ok, finally I had some time for post the BackTrace with the DONT_OPTIMIZE
enabled in the "Compiler Flags" menu of menuselect. 
As a matter of fact, the log is little bit different:
Here the cli log:
