With the simpler scenario I was able to reproduce the confbridge failing to go away. Also I found that it consistently crashes when you try to "confbridge list ..." the confbridge that was not torn down.

Attaching full log with VERBOSE 5, DEBUG 5,(full.txt) and backtrace (backtrace.txt) from the crash.

> I've set up a conference where I'm relying on end_marked=yes to kick all participants when the leader exits.  This results in an error as shown below:
> {noformat}
>  << Hangup on console >>
>     -- <Bridge/0x2364be4-input> Playing 'confbridge-leave.slin' (language 'en')
>     -- Stopped music on hold on SIP/gent_2880-00000002
>     -- <SIP/gent_2880-00000002> Playing 'custom/thank-you.ulaw' (language 'en')
>     -- Executing [1000 at conferences:2] Hangup("SIP/gent_2880-00000002",
> "") in new stack
> == Spawn extension (conferences, 1000, 2) exited non-zero on
> 'SIP/gent_2880-00000002'
> {noformat}
> In this case, the conference leader was the alsa console channel.  Once it was hung up, a non-zero exit status caused the confbridge to go into a bad state showing 0 users:
> confbridge list
> {noformat}
> Conference Bridge Name           Users  Marked Locked?
> ================================ ====== ====== ========
> 1000                                  0      0 unlocked
> {noformat}
> Asterisk has to be restarted to clear this.  In a normal exit, a "confbridge list" would not show conference 1000 because it would have been destroyed.
> If no participants are dialed into the conference, everything closes cleanly when the leader exits.
