Issue with EAGLE_100 with gcc7 and openMPI 2.x

Running EAGLE_100 on our new machine with gcc toolset seems to result in a crash.

Running branch skylake_server_support @ c67f1691

MPI_ABORT was invoked on rank 20 in communicator MPI_COMM_WORLD
with errorcode -1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
