vstinner commented on Oct 4, 2023 Using clang -O0, it works as expected, a single test is skipped:
./configure CC=clang LD=clang --with-pydebug 'CFLAGS=-fno-omit-frame-pointer -O0'
(...)
All 5 tests OK.
Total duration: 1 min 28 sec
Total tests: run=57 skipped=1
Total test files: run=5/5
Result: SUCCESS
vstinner commented on Oct 5, 2023 The issue should now be fixed in 3.11, 3.12 and main branches.
