If you have:

module.f1
   path: path_t

...

    module.f2 = module.f1

Then the initializer for "path" in module_f2 will supply "f1" as the function name for error messages.

It seems like this was fixed somewhere between now and January 2014. I added some tests that should cover these cases in gh-104167.
