[petsc-users] pastix solver break at pastix_checkMatrix

[Gong Ding]

Dear Barry
Sorry, I should complement that
when I set DIFFERENT_NONZERO_PATTERN to the MatStructure, pastix works well.
But it crash for SAME_NONZERO_PATTERN. 
However, I always use SAME_NONZERO_PATTERN before, which works for ksp solvers, mumps, superlu_dist, etc.

Yours
