Conversion from a (object *) to a (char *) produces a pointer to
the first byte in the object (thought of as an array of bytes).
Whether the first byte is most or least significant within a
larger machine integer depends on the architecture.
The numerical address (i.e. what you'd get by casting to an
integer) need not be the same for the two pointer sizes,
although it often will be.
