Description:Simple setup:

Call comes from external asterisk server (pstn2) and then the call goes out with a simple dial through another server (pstn5).

After call is answered I call another extension to listen in on the first channel. This results in a crash every time.

Dialplan:
exten => 38708699,1,Dial(IAX2/pstn5/48999303)

exten => 38701506,1,ChanSpy(IAX2/pstn2-7258)

Se attached backtrace.

Have the same in 218184 when SIP spies on IAX and vice versa. Seems OK SIP/SIP. Not sure about IAX/IAX.

Just before the crash:

Please provide a proper backtrace per doc/backtraces.txt.

You will need to compile Asterisk with DONT_OPTIMIZE in the Compiler Flags options of menuselect.

Once you've reproduced the issue, please run the commands per backtraces.txt.

Thanks!

Take mine gdb_cms.txt - hope it's OK...

Sorry for taking some time. I hope the backtrace is correct now.

1.6.1.10-rc1 crashes as well on chanspy and extenspy

Only assigned to russell for review to determine if this is a blocker for 1.6.1.10, or whether it will need to wait for the next release cycle. Please set to the appropriate status after review. Marking this to you so I don't forget to mention it on Monday.

Actually https://issues.asterisk.org/view.php?id=16045 has seemed to fix this for me!

Thanks for reporting back! I'm going to mark this as a duplicate of 16045 and then close this issue. Please continue to track this issue at ASTERISK-14963
