Research direction

Start with the PyObject_Call C API entry point and review the documentation referenced by BPO 42629. The issue does not identify a source file, test, expected behavior, or concrete reproduction, so first determine the documented-versus-observed discrepancy; done means the behavior and documentation agree with a regression test covering it.
