  • Python built with: CC=clang ./configure --config-cache --with-thread-sanitizer --with-pydebug --disable-gil
  • Run: ./python -m test test_ssl -v -m test_sni_callback_race

Example: https://github.com/python/cpython/actions/runs/27292771649/job/80617491428?pr=151273

Log: 0:07:07 load avg: 6.19 [54/60/1] test_ssl worker non-zero exit code (Exit code 66) -- running (1): test_socket (1 min 40 sec)

Since it's a race condition, the bug doesn't always occur. You may have to run ./python -m test test_ssl -v -m test_sni_callback_race multiple times to trigger the bug.
