This is the same problem as reported in
https://bugs.launchpad.net/dolfin/+bug/799513.

One solution is to downgrade to SWIG 2.0.3. You can do that by letting
Dorsal build SWIG for you. In that case, make sure to rebuild
Trilinos, UFC and DOLFIN. You will need to remove the CMake cache,
that is dorsal_build_dir, for all these project before doing the
rebuild.

Another solution might be to upgrade Xcode, however, I'm not
absolutely sure that this will make it work with SWIG 2.0.8.
