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?
