[issue5945] PyMapping_Check returns 1 for lists

[Guido van Rossum]

Guido van Rossum <guido at python.org> added the comment:

The question is, if PyMapping_Check() returns True, and a list is passed, will the code segfault or raise an exception?  A segfault would be unacceptable; an exception would be acceptable assuming that the code would have raised an exception anyway if PyMapping_Check() had returned False.
