Do not use a kernel without exact predicates. Kernel should be something like CGAL::Exact_predicates_inexact_constructions_kernel. See this entry for more details.
solid.off has some self-intersections due to a degenerate face (that can be removed successfully with the undocumented function CGAL::Polygon_mesh_processing::remove_degenerate_faces() defined in CGAL/Polygon_mesh_processing/repair.h.
