[issue4298] pickle segfault or MemoryError on invalid input

[Hagen Fürstenau]

New submission from Hagen Fürstenau <hfuerstenau at gmx.net>:

On a 64-bit build pickle.loads segfaults on the following bytes. (Same
for pickle.load on a corresponding file.) On a 32-bit build there is
only a MemoryError.

Python 3.0rc2 (r30rc2:67114, Nov 10 2008, 12:09:54)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pickle
>>> pickle.loads(bytes([0x58, 0, 0, 0, 0x54]))
Segmentation fault
