[issue37012] Possible crash due to PyType_FromSpecWithBases()

[Petr Viktorin]

New submission from Petr Viktorin <encukou at gmail.com>:

If the PyObject_MALLOC() call failed in PyType_FromSpecWithBases(), PyObject_Free() would be called on a static string in type_dealloc().

Fixed by Zackery Spytz in pull request 10304. I'm opening the issue retroactively.
