Incorrect solution when running cluster_sparse_solver example problem: cl_solver_sym_sp_0_based_c.c

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.
