I tried using the defined signatures to create a DofMap like this:

UnitSquare mesh(imageSize[0], imageSize[1]);
dolfin::DofMap dofmap("FFC dof map for FiniteElement('Lagrange',
'triangle', 1)", mesh);

But I get a segmentation fault starting with the following warning:

Checking mesh ordering (finished).
*** Warning: Assignment operator for MeshData not implemented.
 *** Process received signal ***
 Signal: Segmentation fault (11)

It seems this patch has already removed the warning:

I have the latest binaries installed. Am I creating the DofMap object
in a wrong way, or is this a bug?
