The interface to MPI_Bcast does not specify a assumed-shape-array dummy
first argument. Consequently, as David points out, the compiler makes a
contiguous temporary copy of the array section to pass to the routine. If
using ifort, try the "-check arg_temp_created" compiler option to verify
creation of temporary arrays.
