MKL scalapack and example1.f

Hello!

I'm trying to start using MKL Scalapack and have downloaded example1.f from http://www.netlib.org/scalapack/examples/.
But it failes to start both on gfortran and ifort:

If mpif77 points to ifort:

$ mpif77 -g example1.f -L$MKL_LIB -lmkl_blacs -lmkl_scalapack_core -lmkl_core -lmkl_intel -lmkl_blacs_openmpi -lmkl_intel_thread -liomp5
$ mpirun -n 2 a.out
forrtl: severe (174): SIGSEGV, segmentation fault occurred

--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 21960 on
node pc7229 exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------

Also with gfortran:

$ mpif77 -g example1.f -L$MKL_LIB -lmkl_blacs -lmkl_scalapack_core -lmkl_core -lmkl_gf -lmkl_blacs_openmpi -lmkl_gnu_thread -liomp5
$ mpirun -n 2 a.out
[pc7229:21994] *** Process received signal ***
[pc7229:21995] *** Process received signal ***
[pc7229:21994] Signal: Segmentation fault (11)

[pc7229:21994] *** End of error message ***
--------------------------------------------------------------------------
mpirun noticed that process rank 0 with PID 21994 on node pc7229 exited on signal 11 (Segmentation fault).
--------------------------------------------------------------------------

I'm using ifort 10.0.026, gfortran 4.4.2, openmpi 1.3.3, Intel MKL 10.0.5.025.
Where can be the problem?
