Message 394574 - Python tracker

> GH-26399 is failing with an access violation on Windows. It's failing in one of the flaky tests. I wonder if the segfault is related to flaky tests somehow...

I created bpo-44252 to track this crash, it might be unrelated to commit dcb8786a9848516e823e090bb36079678913d8d3. Even if it's related, I prefer to track it separated to ease collaboration and focus to this issue to the GC protocol.
