[petsc-users] solve problem with pastix

[hg]

Hello

I got crashed when using Pastix as solver for KSP. The error message looks
like:

Does anyone have an idea what is the problem and how to fix it? The PETSc
parameters I used are as below:

-pc_type lu
-pc_factor_mat_solver_package pastix
-mat_pastix_verbose 2
-mat_pastix_threadnbr 1
