I have the latest from SVN, with my change commented out
and yours applied.  But I get an access violation when I
run the code in release mode, and the standard assertion
in debug mode where EvalFrame has a frame with the
stackpointer unexpectedly set to NULL.  This happens
on the first test in the Python regression test suite.

"Unhandled exception at 0x1e044078 (python25.dll) in python.exe:
0xC0000005: Access violation writing location 0x00000000."
