#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,
 Bryon

 Example Program ***************************************************
 int main(int argc, char* argv[])
 {
         mpi::environment env(argc, argv);
         mpi::communicator world;
         char value[128]={'\0'};
         if(world.rank()==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;
         if(world.rank()==0)
                 was_successful=true;
         mpi::broadcast(world,was_successful,0);
         std::cout<<world.rank()<<" :"<<(was_successful?"Success with
 broacasting boolean":"Failure with broadcasting boolean")<<std::endl;

         std::string bvalue;
         if(world.rank()==0)
                 bvalue="Hello Bryon from boost API with string.";
         mpi::broadcast(world,bvalue,0);
         std::cout<<world.rank()<<" :"<<bvalue<<std::endl;

         return 0;
 }
