Summary:                    Pickup hangs asterisk
Description: 
Asterisk stops to service new calls when someone tries to pickup a call by
pressing *8. Some existing calls are also terminated, although others
continue to work. I still can run any command in the console, but I can't
stop or kill Asterisk. I can kill it only with -9 flag.
I found this trouble in versions 1.8.1, 1.8.2 and SVN.

We upgraded the other day to 1.8.2.3 and are seeing the same issue. When
the client attempts a call pick up we see in messages:

[Mar  8 09:20:40] NOTICE[28904] app_directed_pickup.c: No target channel
found for 613

at that point Asterisk segfaults and restarts.

I have checked features.conf and pickupexten is already commented out and
we use in the dialplan:

; Enable call pickup for hinted stations from any possible source
contexts
exten => _*8XXX,1,Pickup(${EXTEN:2}@a1pub&${EXTEN:2}@a1a&${EXTEN:2}@a1b)

Very hesitate to upgrade to 1.8.4-rc2 and if we downgrade we hit another
issue that causes a restart :( Its looking like we may need to drop back to
1.6 branch; double :(
