Have you made sure that stubs taking more than five arguments need to
be split up into two functions? E.g.:

C-file:

  CAMLprim value add_nat_native(value nat1, value ofs1, value len1,
                                value nat2, value ofs2, value len2,
                                value carry_in)
  {
    ...
  }

  CAMLprim value add_nat_bytecode(value * argv, int argn)
  {
    return add_nat_native(argv[0], argv[1], argv[2], argv[3],
                          argv[4], argv[5], argv[6]);
  }

OCaml-file:

  external add_nat: nat -> int -> int -> nat -> int -> int -> int -> int
                  = "add_nat_bytecode" "add_nat_native"

Notice that the external function needs to be declared such on the
OCaml-side that you name both entry points (for byte- and native code).

That's the only difference that comes to my mind...
