try-finally assertion error

Can't believe you never tried this on your own file :)

python2.7 -m compileall fupy.py && python2.7 fupy.py fupy.pyc
Leads to an Assertion Error

I condensed it down to this code snippet, which leads to said assertion error:

try:
    if a:
        raise b
finally:
    pass

A combination of try-finally and a conditional exception raise. May be simpler, but I did not manage to reproduce the error with a smaller piece of code.
