Summary:                    PrivacyManager generates a core dump when testing
Description: 
Create a test dialplan extension:

exten => 8100,1,Set(CALLERID(num)="")
exten => 8100,n,Answer()
exten => 8100,n,PrivacyManager()
exten => 8100,n,GotoIf(${[${PRIVACYMGRSTATUS} = FAILED]}?:nocid)
exten => 8100,n,NoOp(Number is ${CALLERID(num)})
exten => 8100,n,Hangup()
exten => 8100,n(nocid),Playback(vm-goodbye)
exten => 8100,n,NoOp(Number is ${CALLERID(num)})
exten => 8100,n,Hangup()

Dial the extension and enter a number.  Once entered Asterisk core dumps;
and the following is within the console:

  == Using SIP RTP CoS mark 5
   -- Executing [8100 at test:1] Answer("SIP/1001-00000000", "") in new
stack
   -- Executing [8100 at test:2] Set("SIP/1001-00000000", "CALLERID(all)=""")
in new stack
   -- Executing [8100 at test:3] PrivacyManager("SIP/1001-00000000", "") in
new stack
   -- <SIP/1001-00000000> Playing 'privacy-unident.g729' (language 'en')
   -- <SIP/1001-00000000> Playing 'privacy-prompt.g729' (language 'en')
