Antoine Pitrou <pit...@free.fr> added the comment:
It turns out that the test segfaults:
$ ./python -E -bb -c "import _testcapi; _testcapi.crash_no_current_thread()"
Erreur de segmentation (core dumped)
And here is the backtrace:
Program terminated with signal 11, Segmentation fault.

That's probably because PyThreadState_GET() gets compiled to a simple lookup in
non-debug mode, and doesn't trigger the fatal error.
