[New-bugs-announce] [issue46857] Python leaks one reference at exit on Windows

[STINNER Victor]

New submission from STINNER Victor <vstinner at python.org>:

"./python -X showrefcount -I -c pass" returns "[0 refs, 0 blocks]" as expected on Linux: Python doesn't leak any reference nor memory block.

But on Windows, it still leaks 1 reference (and 1 memory block)!

vstinner at DESKTOP-DK7VBIL C:\vstinner\python\main>python -X showrefcount -I -c pass
[1 refs, 1 blocks]

I recently added a test in test_embed which now fails on Windows.

See bpo-1635741 "Py_Finalize() doesn't clear all Python objects at exit" for the context.
