I also went through the segmentation error guide and couldn't find an answer to this problem.
(I have also tried setting the KMP_STACKSIZE to 25GB and ulimit -s unlimited)
btw, I use ifort 10.0.

amit@sys:~/openmp> mpirun -np 1 ./2009.x
MPI: On host sys, Program /openmp/2009.x, Rank 0, Process 26346 received signal SIGSEGV(11)

You could try the -check and -g options to find out where you have problems. I wouldn't expect to find answers without following up Ron's suggestions about how to dig deeper. In principle, thread checker should be applicable, although it hasn't had much maintenance lately.
Why are you using such an old compiler?
When running 1 mpi process, it shouldn't matter which MPI you are using, but if your MPI is as old as your compiler, you are probably wasting your time.     The current Intel and HP MPI have built-in support for hybrid.
