[issue5180] 3.1 cannot unpickle 2.7-created pickle

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

The pickle was generated by pybench. You can try to display it by running:

./python Tools/pybench/pybench.py --debug -s 27.bench

It fails with the following traceback:

Traceback (most recent call last):
  File "Tools/pybench/pybench.py", line 954, in <module>
    PyBenchCmdline()
  File "/home/antoine/py3k/__svn__/Tools/pybench/CommandLine.py", line
349, in __init__
    rc = self.main()
  File "Tools/pybench/pybench.py", line 888, in main
    bench = pickle.load(f)
  File "/home/antoine/py3k/__svn__/Lib/pickle.py", line 1335, in load
    return Unpickler(file, encoding=encoding, errors=errors).load()
_pickle.UnpicklingError: bad pickle data
