[issue45383] PyType_FromSpec API fails to use metaclass of bases

Tue Oct 5 17:51:26 EDT 2021

New submission from Sebastian Berg <sebastian at sipsolutions.net>:

The PyType_FromSpec fails to take care about MetaClasses.

     https://bugs.python.org/issue15870

Asks to create a new API to pass in the MetaClass.  This issue is only about "inheriting" the metaclass of the bases correctly.  Currently, Python fails to take into account that the bases may be MetaClass and not `PyType_Type` instances.
