Hi, i am trying out the MG preconditioner in PETSc and am encountering some issues. In fact when i use the MG preconditioner i get a segmentation violation. This does not happen with other preconditioners. Running Petsc in debug mode with the -info option did not seem to produce any useful data (at least to me) I thought i'd ask if someone encountered this before i use valgrind. I am using 2.3.3-p8. Or does anyone have a hint on where i could start looking? Again, what bothers me is that the other preconditioner do not throw any sort of error. thanks mat
