Hello.

I'm using Boost 1.46.0 with OpenMPI 1.5.3 under Gentoo x64. I have  
compiled OpenMPI with thread and mpithread option and Boost with MPI  
support. A little testprogram with:

#include <boost/mpi.hpp>
namespace mpi       = boost::mpi;

int main(int argc, char* argv[]) {
     mpi::environment loMPIenv(argc, argv);
     mpi::communicator loMPICom;

     return 0;
}

crashes alway if I run it with "mpiexec -np" (without mpiexec it  
runs). Sometimes the program hangs or creates the message "adress not  
mapped" with "Segmentation fault".

I have recompiled OpenMPI without threads and mpithreads and it seems,  
that the errors are gone.

Is this a problem with OpenMPI or Boost MPI?

Phil
