I'm getting an error in Win64 native code compiler generated code:
output_value: nat too big
What does that mean? Looks like a Marshalling bug?

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.
