It appears the implementation of mpi::broadcast(), according to this post, 
http://lists.boost.org/boost-users/2010/12/64802.php
and I confirm that expects an already built object to call the 
(de)serialization procedure on.

Therefore, this seems a specific issue that mpi::broadcast() may want to handle differently,

could you confirm/correct?
