[Q-e-developers] Problem with trunk and intel-MPI

[Martin Schlipf]

I tracked the issue and it happens somewhere in the subroutine 
read_file(). The error message that I get is

PMPI_Bcast(1635): MPI_Bcast(buf=(nil), count=1, MPI_INTEGER, root=0, 
comm=0xc4000001) failed

which looks to me like we try to broadcast an array that is not allocated.
