Abhay Gupta commented on ASTERISK-27756:
----------------------------------------

Checked the issue . Sequence of event is 
1. Incoming Call comes in Stasis without ANSWER
2. Create a bridge
3. Add the channel in bridge 
4. Destroy bridge 
At this point we get the issue of Failure to impart channel
5. As soon as the channel is Hangup Asterisk segfaults with same back trace
