I would say "correct behavior"; the manual says, about generic
comparisons:
Comparison between cyclic structures may not terminate.
Note that it would be costly to implement exact (structural) comparison of
cyclic structures (with a coinductive definition). What you want is
probably to test for physical equality; you can use the functorial version
of hash tables to do that.
