Do you really get this output twice? It should really only be printed once
by the pcout object in this program. I suspect this has something to do
with the problem.
Separately, can you try the attached patch for
lac/source/petsc_parallel_vector.cc and run the program again? Please
forward the output, maybe this sheds some light on what's going on.
Best
