I have found that with some of our test cases, using more than one MPI rank results in a crash. Way down in the preconditioner code in petsc a Mat gets computed that has "null" for the "productsymbolic" member of its "ops". It's pretty far removed from where we compute the Jacobian entries, so I haven't been able (so far) to track it back to an error in my code. I'd appreciate some help with this from someone who is more familiar with the petsc guts so we can figure out what I'm doing wrong.
