These two tests were failing when building against Python 3.12 because these Integer objects had a refcount of 4294967296 (-1). I didn't dig into it, but I suspect the Python runtime has adopted an optimization to decrease refcounting traffic for these simple objects.

Perhaps related to ...

I was curious and investigated. Whether that is the *exact* change, it seems to confirm your hypothesis that there is special refcounting code for certain types of Python objects. Would you agree with that?

I hope that helps!
