Build a debug version of CPython on Windows.
Build an an extension module linked against this debug CPython's python3_d.dll.
This crashes at runtime with the following error:
ImportError: Module use of python3_d.dll conflicts with this version of Python.
This originates from

It looks like this code doesn't account for the possibility of linking against python3_d.dll when using a debug build.
