Incorrect solution when running cluster_sparse_solver example problem: cl_solver_sym_sp_0_based_c.c

[segmentation_fault]

Unfortunately I am getting the following error when running the provided example, cl_solver_sym_sp_0_based_c.c :

Factorization completed ...
Solving system...
Intel MKL ERROR: Parameter 6 was incorrect on entry to DLASWP.

The solution of the system is:
 x [0] =  0.000000
 x [1] =  0.000000
 x [2] =  0.000000
 x [3] =  0.000000
 x [4] =  0.000000
 x [5] = -nan
 x [6] =  0.000000
 x [7] =  nan

Here is my job submission script:

#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh > /dev/null 2>&1

ulimit -a
ulimit -s unlimited
export OMP_NUM_THREADS=1;

mpirun -np 1 ./a.out

And job submission command:

qsub -l nodes=1:ppn=2 -d . build.sh

Ideally I want to run it on two processors, i.e mpirun -np 2. But that totally errors out with segmentation fault. So I switched to one processor and it gives the errors above.
