When the bug occurs, I see that the Python stdlib abc.py file is loaded twice: the main interpreter builds a code object, and then subinterpreter builds its own code object: same content, but different Python object (at different memory addresses so inequal pointers!). I modified reproducer.c to add "Py_VerboseFlag = 1;" before the Py_Initialize() call. Truncated output: --- ... # code object from /opt/py310/lib/python3.10/abc.py ... # code object from /opt/py310/lib/python3.10/abc.py Traceback (most recent call last): File "<frozen importlib._bootstrap>", line 1027, in _find_and_load ...
