btw, the same problem exists in test_cframe().
See my previous email about the possible correctness of this all.

Subject: [Stackless] Patch for pickle problem on 64bit platforms

Hi all,

The following patch fixes the pickle problem on 64bit platforms:


This problem was causing all pickle-related unit test to fail with
a message like:

"cannot execute invalid frame [..]: frame had a C
state that can't be restored."

(or see http://hhg.to/pickle-fix.txt for example output).

The problem was caused by a PyArg_ParseTuple int/long size
misalignment in cframe_setstate (core/cframeobject.c).
