Description:It looks like a cut and paste error has resulted in ast_request being called twice in wait_for_answer in app_dial.c.  If you get into a call forwarding situation (like a 302 redirect from a SIP phone), this results in two sets of Local channels being created, two of which you are never able to hang up.

****** STEPS TO REPRODUCE ******

[default]
exten => 100,1,Playback(demo-congrats)
exten => 100,n,Hangup
exten => 200,1,Dial(SIP/home)
exten => 200,n,Hangup

SIP/home set to call forward to extension 100

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

loki*CLI> dial 200@default
 == Console is full duplex
   -- Executing [200@default:1] Dial("OSS/dsp", "SIP/home") in new stack
   -- Called home
   -- Got SIP response 302 "Moved Temporarily" back from 69.17.122.227
   -- Now forwarding OSS/dsp to 'Local/100@default' (thanks to SIP/home-777e)
   -- Executing [100@default:1] Playback("Local/100@default-95c7,2", "demo-congrats") in new stack
   -- Local/100@default-95c7,1 answered OSS/dsp
<< Console call has been answered >>
   -- Playing 'demo-congrats' (language 'en')
Really destroying SIP dialog '7ee4d13808ae6bf87a90ca0c5f4cc82b@69.17.122.100' Method: INVITE
