Thanks.  Looks safe to me, Wolfram should comment as well.  I've
applied the patch after removing most of the MALLOC_MEMMOVE
definition.  It cannot be correct since it didn't change the copy
direction.  The macro for now simply calls memmove. If you want to
provide a more complicated, faster version please go ahead.

Thanks,
