Matt Jordan updated ASTERISK-21139:
-----------------------------------

    Description: 
Given the following testing dialplan:

{noformat}
[test_bunker]
  exten => s,1, NoOp(... crash test dummy ...)
  same => n, Answer(1)
  same => n, Set(_access_code=5555097)
  same => n, Set(_bridge_profile=ccb_bridge)
  same => n, Set(_menu_profile=ccb_guest_menu)
  same => n, Set(_user_profile=ccb_guest_user)

  same => n, Read(digits,"hold-or-dial-0",1,i,1,9)
  same => n, GotoIf($[${digits}==9]?makeadmin:startconf)

  same => n(makeadmin), Set(_user_profile=ccb_admin_user)
  same => n(startconf), Set(admin_count=${CONFBRIDGE_INFO(admins,${access_code})})
  same => n, ConfBridge(${access_code},${bridge_profile},${user_profile},${menu_profile})
{noformat}

... with:

{noformat}
[ccb_admin_user]
  type=user
  admin = yes
  marked = yes
  music_on_hold_when_empty = yes
  music_on_hold_class = default
  jitterbuffer = yes
  announce_join_leave = no
  announce_user_count = yes
{noformat}

... run a 2+ participant conference.  Have "Leader" (marked) user drop call.  All guests kicked, as expected/specified.  Now dial back into the conf context.  Asterisk seg faults on READ command.
 
Same behavior if run as an AGI.

Tested on 3 different servers, reproducible in all cases.
