Yes.  Think about it... rlet expands into a %stack-block which just
allocates the right amount of memory for the object you wanted to bind
on the stack.  When the %stack-block exits (i.e., when the rlet exits),
Your pointer is no longer valid, since someone else could use (and
probably already has used) the stack at any time.
