Description
Crash report
What happened?
I haven't seen this before, but I don't think it's new. Rather, I suspect it's a very uncommon race in interpreter finalization. Itmight also be specific to ARM (or more likely there).
The same crash happened in two different tests in test_interpreters.test_stress:
- test_create_many_threaded
- test_many_threads_running_interp_in_other_interp
Fromhttps://buildbot.python.org/#/builders/234/builds/6611 run on the "aarch64 Fedora Stable Clang 3.x" buildbot worker:
