[issue46451] Tracing causes module globals to be mutated when calling functions from C

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

Can you reproduce this in pure Python?
If not, can you produce a minimal reproducer using just NumPy?

If you can't do either, I'm going to have to assume that this is a NumPy or Pandas bug.

Maybe NumPy or Pandas is accessing CPython internals, but not via the C-API, and those internals changed between 3.9 and 3.10?
