Hi Adrian,

I put in a test for redistribution with overlap, Plex test ex12, test 7.
You can run it using

  make -f ./gmakefile test search="dm_impls_plex_tests-ex12_7"

and see the output in src/dm/impls/plex/tests/output/ex12_7.out. The second
DMPlexDistribute() call
is made on a mesh with overlap.

If this is not a solution, can we make a small test that goes in ex12 that
shows what is wrong?

  Thanks,

     Matt

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
