Milestone:  Boost 1.37.0          |   Component:  mpi

----------------------------------+-----------------------------------------
 When building MPI datatypes for enumeration types for which
 is_mpi_datatype is true, Boost.MPI ends up building a broken MPI datatype
 that causes segmentation faults. The problem seems to be that
 load_enum_type and save_enum_type (in boost/archive/iserializer.hpp and
 boost/archive/oserializer.hpp, respectively) actually perform the
 serialization call on an "int" rather than on the enum itself, causing the
 mpi_datatype_oarchive to receive an address on the stack.

 Full test case is attached.
