PYTHONMALLOCSTATS=1 fails with fatal error at Python exit #111499
Description
Py_FinalizeEx() calls _PyObject_DebugMallocStats() which calls indirectly _PyInterpreterState_GET(). Problem: at this point, there is no "interpreter" anymore, and so _PyInterpreterState_GET() fails with a fatal error.
It's a regression introduced by commit df3173d. Python 3.12 is also affected.
Reproducer:
$ PYTHONMALLOCSTATS=1 ./python -c pass
Small block threshold = 512, in 32 size classes.
(...)
Total = 262,144

Fatal Python error: _PyInterpreterState_GET: the function must be called with the GIL held, after Python initialization and before Python finalization, but the GIL is released (the current Python thread state is NULL)
Python runtime state: finalizing (tstate=0x0000000000ae7550)
Abandon (core dumped)
