The result can be representable by ptrdiff_t
because the result is number of longs.
The array is bit larger than 2**31 bytes.
So the result is bit larger than 2**29.
It is representable in signed.

ptrdiff_t is defined as a signed type so is the subtraction of two pointer
types.

Oops. It wrapped.
But changing the type of nelem to size_t doesn't change the situation.
nelem * sizeof(l

nelem*sizeof(long)
Wraps so what do you expect? This is the correct behavior really.
