I think that's the normal behavior. Why should a primitive call "pollute"
the Smalltalk stack if it doesn't fail? The recently used primitives are
listed separately.
Most recent primitives
digitCompare:
digitDiv:neg:
>=
digitCompare:
digitDiv:neg:

All senders of #\\\ in my image have your initials. It's a bit suspicious
that Integer >> #reciprocalModulo: doesn't normalize v after the loop, but
it's possible that #- will do it anyway. In the other user - Integer >>
#slidingLeftRightRaisedTo:modulo: - the result is normalized via
#normalize.
