[Jython-dev] try-except+return bug

[Erik H. <er...@py...>]

consider the following function:

def f():
  try:
    return 1
  except SomeException:
    return 2
  except:
    return 3

when i try to call this in jython, running on the jvm included in
win 2000, jython will die. problem seems to be that you cant have
a return in the try block if you have returns in all of the
following excepts.

this works fine with other jvms ive tried, so i guess this is a bug
in ms' jvm?

Yes, it is seems to be a MS-only issue. Your small example made it a lot
easier to track down (it is the same problem that have prevented the use
of jview with jythonc). A fix have been commited to CodeCompiler.java.

Thanks for reporting the bug with such a small test example.
