So, does it look like a logic error or like a problem with openMPI
installation?
In openmpi MPI_ANY_TAG==-1, so they're both set to the right thing,
not waiting for the a message that will never come.
Could you, after attaching the debugger, try stepping forward in both
processes, and make sure they're both hanging, not infinite looping?
