cluster_sparse_solver discrepancy

Hello,

I'm trying to solve a general system with CPARDISO. When using two processes, there is no issue if I don't use the coefficient array during the solution phase. When using only one process, then I get a segmentation fault. Could you give me some insight into this issue, please ? Thank you in advance.
