#2485: MPI broadcast issue
 Reporter: bryon.robidoux_at_[hidden] | Owner: dgregor
     Type: Bugs | Status: new
Milestone: Boost 1.38.0 | Component: mpi
  Version: Boost 1.36.0 | Severity: Showstopper
 Keywords: broadcast MPI |
 The broadcast function is crashing and I can't see anything that I am
 doing wrong. Below I have the code and output to a very simple program
 that I used test the boost API.

 I compiled the boost libraries using Visual Studio 2008 SP1. I linked the
 MPI library against msmpi that is provided with the HPC server 2008 SDK. I
 ran this on a single HPC server 2008 box, so there is no cluster involved.
 It is the simplest case possible.

 Thanks for your help,

 Example Program ***************************************************
 int main(int argc, char* argv[])
         mpi::environment env(argc, argv);
         mpi::communicator world;
         char value[128]={'\0'};
                 strcpy(value,"Hello Bryon from C API\0");
                 cout<<"start "<<value<<endl;

         MPI_Bcast(value,12 , MPI_INT, 0, MPI_COMM_WORLD);
         std::cout<<world.rank()<<" " << value<<std::endl;

         bool was_successful=false;
         std::cout<<world.rank()<<" :"<<(was_successful?"Success with
 broacasting boolean":"Failure with broadcasting boolean")<<std::endl;

         std::string bvalue;
                 bvalue="Hello Bryon from boost API with string.";
         std::cout<<world.rank()<<" :"<<bvalue<<std::endl;

         return 0;

 Output ********************************************************
