> Does the Ocaml implementation make guarantees about the stable representation of floats? In particular, if I use Int64.float_of_bits to create a particular NaN representation, am I guaranteed that its bit pattern is maintained no matter where the value is stored or passed?

I don't remember exactly but I think there may be issues with marshaling. A quick search with in the bt leads to:
