Does code ever work differently in the top-level than when compiled (with
ocamlc)? Should it?

I think everyone would agree that there are caveats here but this is a
question of trade-offs. So the question should be "how can we improve upon
the current implementation?". To which the answer, for me at least, is "I
can't".
There are many pitfalls associated with equality in OCaml but the existence of
polymorphic comparisons is easily justified by their usefulness, IMHO.
