For me it crashes after
  import AA, gc
(Win2k Prof, SP1, MSVC6.0)

I'm not really sure, but it seems your code does not crash any longer
if you remove the Py_TPFLAGS_HAVE_GC from your definition of class_metatype_object.

This flag *will* be set by PyType_Ready(); I guess it is inherited
from the base type (PyType_Type in your case).
