Hi,

I don't know if it can help, but I attached a minimal (ok, let say 
small) example that reproduces the problem without the mpi test nor 
boost code.
It's basically a minimized ~100loc version of bjam.
I sent it to intel so they can investigate, since mpiexec.hydra might be 
part of the problem. Although I think bjam should be able to deal with 
it since the mpi test passes on the command line.
