Comment (by simonpj):

 > What is even worse, this bug prevents us from refactoring the code to
 separate module

 That's odd.  The original report is about ordering declarations within a
 single module.  Can you give a repro case for how refactoring your code
 into separate modules makes things fail?  Thanks!
