[asterisk-users] Hangup handler gosub error with asterisk 16.4.0.

[Harley Peters]

I am receiving the following errors on any hangup handler subroutines.

[2019-05-31 18:22:13.958] VERBOSE[23943][C-00000009] app_stack.c:

Dialplan:
exten => 
_1NXXNXXXXXX,n,Set(CHANNEL(hangup_handler_push)=PreventForwardingLoop,s,1))


[PreventForwardingLoop]
exten => 
s,1,Set(DELETEKEY=${DB_DELETE(PreventForwardingLoop/${USER}/${CALLERID(num)})})
exten => s,n,Return()

This is one example it fails on all of them.

I have no problems with asterisk-16.2.1 and earlier.
Any idea what the problem is or is this a bug?
