Description:using Congestion(0) in dialplan is appearing to leave pri channels unavailable.

Causing a PRI restart when no channels are actually in use, causes multiple messages to appear on console as below.

! Unknown IE 50 (cs5, Unknown Information Element)
   -- Accepting call from '21496205' to '9147' on channel 0/31, span 1
   -- Executing [9147@incoming:1] Congestion("DAHDI/31-1", "0") in new stack
 == Spawn extension (incoming, 9147, 1) exited non-zero on 'DAHDI/31-1'
   -- Hungup 'DAHDI/31-1'

[Jul 30 11:52:16] ERROR[27574]: chan_dahdi.c:10723 dahdi_pri_error: Can't destroy call 0!

I can only get it to happen when <u>Accepting call</u> happens after the Hangup.


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

dialplan code:

exten => _914X,1,Proceeding()
exten => _914X,n,Congestion(0)

Asterisk SVN-trunk-r209484 it gets much worse.
DAHDI Version: 2.2.0 Echo Canceller: MG2

After the first execution of 'Congestion(0)' no further inbound calls can be made.

dialplan is slightly different, as it's on another box.
;congestion
exten => 8696,1,Congestion(0)

Asterisk also segfaults, but with DON'T OPTIMIZE on, I get a core dump but it seems empty??

<b>BUT</b>: If compiled with DON'T OPTIMIZE, MALLOC DEBUG and DEBUG THREADS I get the following console output, thus am able to make multiple calls.
