The likely culprit is the set_next() loop.  Perhaps it is never safe to use set_next() because any lookup can callback to __eq__ which can mutate the set.

Since set_isdisjoint() method isn't a mutating method, that is the easiest place to start investigating.  Try disabling the exact set fast path to see if the issue persists.
