I tried your test programs on a M1 Mac running macOS 11.1 with the latest macOS universal2 Pythons available from (, 3.9.1 and 3.10.0a4, and both produced the same (correct) result as in your 3.8 example.  Are you sure the brew Pythons are using the macOS 11 system libffi and not their own or older version?
