Summary: Py_SAFE_DOWNCAST assert in marshal.c

Initial Comment:
In a win32 debug build (compiled with VC++ 6.0) of
Python 2.2.0 using the default options, the
Py_SAFE_DOWNCAST assertion check fails on line 64 of
marshal.c when c is 0x8c.  The VC++ quick watch window
displays 0xffffff8c as the value of the expression
'(int)(char)c'.  The following code will trigger the
assertion:

import marshal
marshal.dumps([0x8c] * 1000)

I am downloading the latest VC++ service pack now to
see if that makes a difference.

Unless I'm much mistaken, this is a dup of:

[ 588452 ] $DEBUG_PYTHON -O freeze.py broken

which was fixed just a few weeks ago.
