New submission from Jeffrey Harper <jhar...@yapdc.com>:
When a bytes object is pickled with 3.1 and then unpickled with 2.7, the
results are incorrect. The example below shows that pickling
b'abcdefg' in 3.1 and then unpickling in 2.7 produces the string
'[97L, 98L, 99L, 100L, 101L, 102L, 103L]'
The unpickling operation should return 'abcdefg'.
