Summary:                    chanspy - crashes Asterisk
Description: 
duplicated bug from: 0011770 and 11654

Issue 11654 have been closed with comment:

"Fixed in 1.4 as of revision 98975."

but svn reports no revison 98975. 

  svn co -r 98975 http://svn.digium.com/svn/asterisk/branches/1.4
asterisk-fixed
  svn: REPORT request failed on
'/svn/asterisk/!svn/bc/98956/branches/1.4'
  svn: No such revision 98975

I've updated to most recent version from:

svn co http://svn.digium.com/svn/asterisk/branches/1.4 asterisk-svn/ 

Asterisk SVN-branch-1.4-r97889

and it still crashes. I can't reopen issue 11654 so I create new one.

Asterisk freshly compiled and installed.
All calls using G.711 ulaw.
One SIP extension is running chanspy.
No other calls active.
One SIP call comes in (it's from a cisco AS5300 gateway)
The call is answered as it was to the main number.
The system runs an AGI to process CID and does a few other things.
Auto Attendant starts playing (office hours etc, using Background for
playback)
The AA message continues to the next step (using Background playback
again)
And then just as the next message should start playing, Asterisk crashes.
No error messages on the console.
No DTMF keys were dialed at any time.

Asterisk on the same system does not crash when NOT using chanspy.


full backtrace attached uploaded.
