[issue5180] 3.1 cannot unpickle 2.7-created pickle

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

The bytes/string issu was a red herring: with pickle.load(open('27.bench', 'b')), I get the same stack trace as from command line pybench invocation.


>>> pickle.load(open('27.bench', 'rb'))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/sasha/Work/python-svn/py3k-commit/Lib/pickle.py", line 1321, in load
