Trying this version of uncompyle2,

$ git rev-parse HEAD

$ uncompyle2 md5.pyc                     
...

Trying wibiti's version,

$ uncompyle2 md5.pyc         
...

Thank you for reporting this bug. I think all your .PYC file have the same problem ? I wasn't able to reproduce the bug. But I think it's a cast issue in my marshal module.

unpack('l' instead of unpack('i'

I've push the modification, tell me if it's fixed.

I'm working on a big code refactoring for handling python 3.X decompilation and I'll try to get ride of a big part of uncompyle2 (walker/spark) wich are slow.
