The following program segfaults under the C-codegen:

val a = Int64Array.tabulate
        (valOf Int.maxInt, fn i =>
	 Int64.fromInt i)
val i = Int64Array.sub(a, (valOf Int.maxInt) - 2)
val _ = print ((Int64.toString i) ^ "\n")


gdb shows the segfault at:
	X(Int64, P_0, I32_0) = I64_0;
which seems consistent with an overflow when computing the address of the
location into that long long array.
