[New-bugs-announce] [issue35337] Check index in PyTuple_GET_ITEM/PyTuple_SET_ITEM in debug mode

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

I propose to add assertions to PyTuple_GET_ITEM/PyTuple_SET_ITEM in debug mode to check the index when Python is compiled in debug mode (./configure --with-pydebug).

This change is backward incompatible when PyTuple_GET_ITEM/PyTuple_SET_ITEM is used on a structseq with unnamed fields. Well, that's a bug in the user code, PyStructSequence_GET_ITEM/PyStructSequence_SET_ITEM should be used instead.
