#2220: Stack overflow in get_mpi_datatype() for struct declared as primitive_type

 Reporter:  Evgeny        |       Owner:  dgregor
     Type:  Bugs          |      Status:  new    
Milestone:  Boost 1.36.0  |   Component:  mpi    
  Version:  Boost 1.36.0  |    Severity:  Problem
 Keywords:                |  
--------------------------+-------------------------------------------------
 struct MyStruct { int dummy; };

 BOOST_IS_MPI_DATATYPE(MyStruct);
 BOOST_CLASS_IMPLEMENTATION(MyStruct,primitive_type);
 ...
 get_mpi_datatype<MyStruct>() // produces stack overflow

 ## Call stack:
 get_mpi_datatype<MyStruct>();
 mpi_datatype_map.datatype<MyStruct>(...);
 mpi_datatype_oarchive::mpi_datatype_oarchive(const T& x);
 *this << x; //this serialization in turn calls get_mpi_datatype()

 Possible solution: use another mpi_datatype_oarchive constructor with no
 serialization (only for MPI_Type_struct() to be called)
