Behavior is undefined. For details, read the Chapter 18 "Interfacing C
with Objective Caml" of the reference manual. To understand what is
happening, read the section 18.2 (the value type) - or read the source
of the runtime system.

And there is a reason for that. The whole philosophy of Ocaml is
static typing, which the OCaml team pushes to the extreme (for
instance by refusing dynamic casting or class checking for objects).

I miss more dynamic ability of the object part of Ocaml (even if this
means having a tree of classes, not a forest, and reject multiple
inheritance).
