[New-bugs-announce] [issue36531] PyType_FromSpec wrong behavior with multiple Py_tp_members

[Eddie Elizondo]

New submission from Eddie Elizondo <eduardo.elizondorueda at gmail.com>:

If a user accidentally defined more than one Py_tp_members in the spec, PyType_FromSpec will ignore all but the last use case. However, the number of members count will cause the type to allocate more memory than needed. This leads to weird behavior and crashes.

The solution is a one line fix to just restart the count if multiple Py_tp_members are defined.
