phase 13 does not work in cluster_sparse_solver

Hi:

    I take mkl/examplescluster_sparse_solver/cl_solver_unsym_distr_c.c and compile it with mpic++ -cxx=icpc -mkl -xHost and it works well. From the mkl document, I know that I can combine phase 11, phase 22 and phase 33 together to phase 13. However, after I use mpiexec -n 2 to run the later case, I get:

Fatal error in PMPI_Bcast: Other MPI error, error stack:

PMPI_Bcast(1606)......: MPI_Bcast(buf=0x7fff159c2100, count=100, MPI_LONG_LONG_INT, root=0, MPI_COMM_WORLD) failed

MPIR_Bcast_impl(1458).:

MPIR_Bcast(1482)......:

MPIR_Bcast_intra(1253):

MPIR_SMP_Bcast(1167)..: Failure during collective

I use mpicxx for MPICH version 3.1 and mkl 11.2, icpc 15.0.0 on linux64

I want to ask is it a bug?
