Ok, here is a trivial example:

In the Callee: A->(itself)

In the caller: B->C->itself

Your mapping should provide:

A->B  (not sure about this one, is there a better way?)

I don't know how this example could be manufactured in code, but I'm sure 
there are more complex cases which need the same principle...
