Hmm .. found it: in ocaml/otherlibs/num/nat_stubs.c,
this code is wrong:

#ifdef ARCH_SIXTYFOUR
  len = len * 2; /* two 32-bit words per 64-bit digit  */
  if (len >= (1L << 32))
    failwith("output_value: nat too big");
#endif

because 1L << 32 will overflow on _WIN64 because long
integers are still only 32 bits.
