Title:
  Assembling over subdomain fails

Status in DOLFIN:
  Confirmed

Bug description:
  Following setup:

I have a mesh (with FunctionSpace V) and a submesh (with FunctionSpace W). Assembling a linear form on V over this subdomain involving a coefficient from W will fail.

I think the problem is that Dolfin would like to evaluate the function from W at the boundary of the subdomain. Maybe due to rounding errors this point lies outside the subdomain and the evaluation fails.

It does not happen, if W is a CG or DG space.
