Details - The starcdreadertest fails with a double free error (log attached).  Tracking
that down, I found that it is generated during exception unwinding: when the
starcdreader calls GridFactory<UGGrid<3> >::creategrid(), that calls
GridFactory<UGGrid<3> >::detectBoundarySegments() which executes

  DUNE_THROW(GridError, "The grid is not consistently oriented!"
             << "  Mismatch at element face: " << v);

During unwinding the GridFactory object's destructor is called.  The
destructor tries to free the UGGrid which somehow results in the double free
error.

My suspicion is that the UGGrid object is not always in a consistent state
during construction by the GridFactory, so it cannot be destroyed cleanly.  I
don't know enough about UG to go on from here, however.
