Content
I looked at the coredump with Pablo. In short, the main thread is calling Py_Exit() to exit the process and so released memory, and a daemon thread does crash on calling PyEval_RestoreThread() because tstate memory was freed. The question is now if this bug is a regression compared to Python 3.7 or not. I'm trying to reproduce it on Linux by adding "sleep(1)" before exit, but my attempts are unsuccessful so far.
