Ensure that the -static-libcxa flag is used when you use mpirun.mpich to launch a C or Fortran
program.
The following is a C example called vtjacobic:
# mpirun.mpich -np 2 ~/xc_PDE_work/ITC_examples_xc6000/vtjacobic
warning: this is a development version of HP-MPI for internal R&D use only
/nis.home/user_name/xc_PDE_work/ITC_examples_xc6000/vtjacobic: 100 iterations in

/nis.home/user_name/xc_PDE_work/ITC_examples_xc6000
mpirun exits with status: 0
The following is a Fortran example called vtjacobif:
# mpirun.mpich -np 2 ~/xc_PDE_work/ITC_examples_xc6000/vtjacobif
