Destructor of boost::mpi::environment should not throw exception

[anonymous]

The destructor of boost::mpi::environment uses the BOOST_MPI_CHECK_RESULT macro to invoke MPI_Finalize.

BOOST_MPI_CHECK_RESULT(MPI_Finalize, ());

If MPI_Finalize does not return MPI_SUCCESS, the macro will throw boost::mpi::exception. However, it is not a good idea for a destructor to throw.

I suggest the destructor just call MPI_Finalize() without using the MACRO
