    Research direction

    Start with the attached crashWin3.9-2021-08-12.zip, which contains a snapshot and test file, and reproduce the deep-call-stack crash on Windows. Trace the failure in the Python 3.9 interpreter and establish a regression test; done means the supplied case no longer crashes.
