Python for Windows is built using MSVC, which uses UCRT, m2w64 uses the older MSVCRT. This can lead to segmentation faults. Further, conda-forge defaults to Flang for Fortran code. This requires some fragile workarounds to set compiler names, etc.
The build routines should be updated to compile the extensions using MSVC and Flang on Windows.
