Description
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.
