[asterisk-users] ael context ~~s~~ in macros broke Dial() U() option in 1.6.2.17.2 and newer

[Mark G Thomas]

Hi,

I think this must be a bug introduced with 1.6.2.17.something.

When I upgrade from asterisk-1.6.2.16.1 to asterisk-1.6.2.17.2 or 1.6.2.18,
my AEL Dial() commands with the "U" options fail with the following error:

[May  3 12:05:54] ERROR[6300] app_stack.c: Attempt to reach a non-existent 
    destination for gosub: (Context:screen, Extension:s, Priority:1)

Here are the segments of the ael:
---------------------------------------
  ...
  Dial(${MARKCELL},30,tgU(screen));
  ...

  macro screen() {
    Wait(0.5);
    Read(ACCEPT,followme/options,1,,1,20);
    if( "${ACCEPT}" = "1" ) {
        Background(connecting);
    } else {
        Set(GOSUB_RESULT=CONTINUE);
    };
    return;
  };

And, here is the dialplan created from my above ael. The change is obvious,
but I'm not sure if there is some way I can fix this in my AEL, or if this
is just a bug that needs to be fixed.

asterisk-1.6.2.17.2 and asterisk-1.6.2.18:
