MPI does not magically cause all processes to call MPI_Bcast behind the scenes for you. You must ensure that every process in the communicator explicitly invokes MPI_Bcast. You can do whatever logic you want (to include "if" blocks, etc.) as long as they all call MPI_Bcast.
To be clear: all MPI collective operations must be explicitly invoked by every process in the target communicator.
