Inizia da Lib/test/test_dtrace.py, in particolare da SystemTapOptimizedTests.test_gc e dai relativi helper run_case/trace. Riproduci la configurazione aarch64 Fedora Stable e verifica le PR collegati gh-156424 e gh-156755; il lavoro è completato quando il test non fallisce più perché il Python compilato non riesce a individuare libpython3.15d.so.1.0.
