The searched procedure/function is not a class procedure or function.

Where do I say that?

Yes, very quickly!

I switched off optimizations.
I think I am able to handle more than one way to find a call to a 
function/procedure. But at this time I found only one way in my program so 
far. So there was no need to search for other ways...

I can easily adopt the code then.
There are not many different ways for a call.
