Please see if the patch for https://reviewboard.asterisk.org/r/1323/ actually fixes this issue.</pre>

Example dialplan below causes a segfault as ast-hangup removes the same channel as is being picked up.
How to crash it!
dial 801 from 1 phone.
from 2 phones simultaneously dial 800.
segfault!
exten => 801,1,NoOp(Local pickup debug: Ring Phones)
exten => 801,n,Dial(Local/823@en-phone&Local/824@en-phone)
exten => 800,1,NoOp(Local pickup: Pickup through Localchan call)
exten => 800,n,Dial(Local/824@en-pickup&Local/823@en-pickup)
[en-pickup]
exten => _[0-9*#]!, 1, PickupChan(Local/${EXTEN}@en-phone)
[en-phone]
exten => _[0-9*#]!, 1, Dial(SIP/gxp-${EXTEN},20,rwt)
will remove red blobs, and perhaps ast_pickup_active() test.</pre>
