Description:when we tried the Passive Listening (listening the users using the chanspy option) and when tried listening the users  the asterisk server getting crashed , and saying that core segmentation fault.
Scenario :=
1. 2 users are in Conversation,
2. tried listening the conversation by using he chanspy , i.e. by pressing * we can move to the another user and listen the conversation.
3. using '*' listened the first user and then pressed '*' to listen another user and then pressed '*' , now the server gets crashed by saying core Segmentation fault. .
4. But expected to listen the user 1.

This can be easily reproducible. In the additional information fault i have given the steps and other things. I have attached the "bt", "bt full" and "threads all apply" outputs.



****** ADDITIONAL INFORMATION ******

Instructions for using passive listening :-

Thanks for your replies and for fixing the bug. I have checked with the changes made code and ow it seems to be working fine without any asterisk server crash (core segmentation fault).

While trying the passive listening (listening the conversation one by one by pressing '*' key ) , once i have listened all the users and then if i continued to listen from the first user , i am getting some  6 seconds delay to listen the user. Is this a normal functionality and the delay is normal ?? just need to confirm that .

Thanks.
