Summary:                    Crash in ast_cdr_start() when Local channel is
involved
Description: 
Scenario: a SIP call arrives and get split into several branches using
Local channel. A callee in one of the branch answers the call and then
hangs up. Asterisk crashes at point when callee hangs up and gdb suggests
(AFAIU) that crash happened while in the ast_cdr_start().
This happens only if hangup initiated by callee. If hangup initiated by
caller then everything's fine.

This can be duplicated without dialing multiple local channels. It looks
like the scenario goes like this:

exten => 17189282005,1,Dial(Local/111 at fork-xyz)

SIP/poly_650_01 calls extension 17189282005.

(chan, peer  chan, peer)
SIP/poly_650_01 <-> Local/111 at fork-xyz-94a6,1 <->
Local/111 at fork-xyz-94a6,2 <-> SIP/xyz011101

The two local channels are hung up leaving:
SIP/poly_650_01 <-> SIP/xyz011101

I haven't looked much closer, but the orig_chan_cdr in ast_bridge_call
looks very suspect. One of the peers is definitely not valid since it was
one of the local channels.
