I remove Mark from the issue. I may open later a different issue for
tb_frame.f_globals=None, but it's unrelated to this bug.
I can reproduce the issue with a small hack to make GC collections make likely:
diff --git a/Lib/site.py b/Lib/site.py
index 939893eb5e..4103792e84 100644
--- a/Lib/site.py
+++ b/Lib/site.py
@@ -672,3 +672,6 @@ def exists(path):
if __name__ == '__main__':
_script()
+
+import gc
+gc.set_threshold(5)
With this patch, it becomes trivial to reproduce the crash on Linux:
$ ./python -m test test_ssl -m test_ssl_cert_verify_error -v
(...)
Fatal Python error: Segmentation fault
Current thread 0x00007fd0f72a8640 (most recent call first):
File "/home/vstinner/python/3.10/Lib/traceback.py", line 132 in
format_exception
File "/home/vstinner/python/3.10/Lib/test/test_ssl.py", line 262 in
handle_error
File "/home/vstinner/python/3.10/Lib/test/test_ssl.py", line 2401 in wrap_conn
(...)
So the problem is that _ssl.SSLError type traverse function is NULL.
