parallel-dofmap-disconnected-meshes

[Garth Wells]

I get seg fault when building the dof map in parallel for a mesh which has disconnected regions. It works fine on one processor.

I'm using a Python solver, so I'll need to build a C++ version in order to dig deeper.

I've added a C++ example that fails in parallel to

  lp:~dolfin-core/dolfin/sandbox

in the directory 'disconnected_mesh'

I committed a small fix which deals with completely disconnected meshes, but meshes with a connected vertex but no connected facets still fails. Problem is that the interior boundary code checks facets.

I'll take a closer look as soon as I get a chance, but probably not
until next week.
