I ran the example code with renumbering on my macbook with mpich + osx 10.13 and I get same type of crash when running in parallel.
I recently switched to mpich since I was having some memory leak with openmpi in one of my applications (not deal.II related). I have not extensively tested my deal.II programs with mpich yet.
