Instead of (U*)1, what about (U*)cu where
  char cu[sizeof(U)];
as suggested by http://lists.boost.org/MailArchives/boost/msg33483.php?

I can see maybe the 1 in (U*)1 seems suspicious, but it's only there to
allow some difference between the U* and T*.  Anyway, the cu char vector
seems perfectly OK to me since it can always be converted to a U* via
placement new.
