Hello dev-team,

I wrote simple program to test different solvers. It reads matrix and 
rhs and solves system. That is it.
I tested this program using PETSc's interface to MUMPS (LDLt), 
SuperLU_Dist (LU) and it works well giving right solution, however when 
I switch
to PaStiX (LLt) the solution is zero. The output is attached.
The matrix is SPD and has condition number of 16, there should be no 
I use petsc-dev.
How could I figure out where is the problem?

Thanks in advance.
