Summary:                    Crash in cdr code in specific one-touch parking
scenario
Description: 
Asterisk crashes in cdr code in ast_bridge_call() in the following
one-touch parking scenario: A calls B, B answers, A dials feature code to
park B. Asterisk plays MOH to B and parking announcement to A. Now if B
hangs up during parking announcement is being played to the A then asterisk
crashes immediately after it ends playing parking announcement to A.
I'm attaching backtrace in bt.txt

---------------------------------------------------------------------- 
Hold the presses. Plan C still survives, but crashes when the dialing party
gets parked, and hangs up while the answering party is getting the
announcement. It's a matter now of AST_PBX_KEEPALIVE being used to keep you
away from accessing CHAN.
Another patch will be forthcoming...
