[petsc-users] question about partitioning usage

I create it to partition my input unstructured mesh, then I destroy
it. It is so separated from the rest of the code, that I could even
delegate it to a separate program.
But then, as shown in the other thread, I somehow get an assertion
fail from parmetis much later in the code, when creating solver
contexts. Why is this happening if the MatPartitioning object was
destroyed?
