[Asterisk-Users] Macros not working as expected with extension "h" in some circumstances

I don't think I'm using it in an improper way, and in any case take 
another look at the logs I included; the "GotoIf" isn't even being 
parsed; processing is stopping at the SetVar line, and not the GotoIf 
line.


 From README.variables:
  exten => s,5,GotoIf,"$[${varc} = 6]?99|1:s|6"

 From "show application GotoIf"
    GotoIf(Condition?label1:label2): Go to label 1 if condition is
true, to label2 if condition is false. Either label1 or label2 may be
omitted (in that case, we just don't take the particular branch) but not
both.  Look for the condition syntax in examples or documentation.

I have omitted the condition for 0, and it correctly behaves as the 
documentation describes.  If "1", then jump to extension "s" priority 
6. If condition "0" then proceed to next priority.

  The "|" character is what is used in the example to separate the 
extension from the priority, and the ":" is used to separate the "1" 
and "0" cases.   Just to be complete about it, I did try putting in 
an explicit jump to next priority on condition "0", and it results in 
the same undesired results (processing stops after priority 1 in the 
macro.)

  So, I still may be doing something wrong, or this may be a bug, but 
I don't think it's a mis-use of the GotoIf statement according to 
what I can find in the docs and other examples.
