Hi,

I just wonder, what is wrong with DM ex9 (see below)? What does the "statement has no effect" message mean, and how can it be fixed? I copied the code in question from http://www.mcs.anl.gov/petsc/petsc-current/src/ksp/ksp/examples/tutorials/ex18.c.html, and it appears to work as expected. It also seems that other examples use PetscOptionsBegin() the same way.

Thanks.

Håkon
