Follow-up Comment #1:

This one was pretty obscure and hard to track down.  It turned out to be an
issue in variable renaming (aliasing) when expanding a macro template. 
Specifically, when nested definitions with the same name (f1) where f1 is a
macro parameter.  The reference to f1
in the body of f3 got resolved to the wrong definition. (Of course nested
definitions with the same name is pretty questionable in human-written code,
though I guess it could be reasonable in macro-generated code.)

Thanks for the test-case - It checked it in along with the fix,
