The root cause might be some issue with the JIT: if there is a bug there, then we can get this kind of nonsense-looking result. It is however completely impossible to know what the issue is just by looking at the Python code. Usually it takes a lot of efforts inside gdb to figure these bugs out. The good news is that these issues are extremely rare: much less than one per release, in average. It's possible that we fixed a JIT issue between PyPy 5.3 and PyPy 5.9 and that this issue caused the misbehavior you're observing. All I can suggest is to continue trying with PyPy 5.9. A bientôt, Armin.
