It doesn't look like this is a problem with either MPI_Bcast or your
call to creat. One of the processes exited with a status of 4 before a
call to MPI_Init. Do you have a call to exit(4) or exit(errno)?
Either could cause the problems you are seeing. You might want to look
at the "Debugging MPI Programs" section of the LAM/MPI FAQ for ideas on
how to debug your application.
