Hello,

 I have the following code:

#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE mpi_functionality
#include <boost/test/unit_test.hpp>

#include "mpi.h"

struct MPI_Functionality_Fixture
{
  MPI_Functionality_Fixture()
  {
    m_argc = boost::unit_test::framework::master_test_suite().argc;
    m_argv = boost::unit_test::framework::master_test_suite().argv;
  }

  int m_argc;
  char** m_argv;
};

BOOST_FIXTURE_TEST_SUITE( MPI_Functionality_TestSuite, 
MPI_Functionality_Fixture )

BOOST_AUTO_TEST_CASE( mpi_functionality_parenv_init )
{
  MPI_Init(&m_argc,&m_argv);
}

BOOST_AUTO_TEST_CASE( mpi_functionality_parenv_finalize )
{
  MPI_Finalize();
}

BOOST_AUTO_TEST_SUITE_END()

The code compiles fine, but I have the following problem when I try to run it. 
When I run as 

  'mpirun ./my_executable' or 'mpirun -np 3 ./my_executable'

everything goes fine. On the other hand, when I run as

  ./my_executable

I get the following error: 
unknown location(0): fatal error in "mpi_functionality_parenv_finalize": 
unrecognized signal

Outside of Boost, it is perfectly possible to write  a program which calls 
MPI_Init and MPI_Finalize and it does not have to be used with mpirun.
I wonder if this (different) behavior of Boost test is normal. I did not find 
any remarks regarding Boost test and mpi in the tutorial.

Best regards,
