Hello,
I have the following code to repair the candy_bowl.obj file:

typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;

bool repairOBJFile(const char* filename)
{
        std::cerr << "repairOBJFile " << std::endl;
        std::ifstream input(filename);
        if (!input)
        {
                std::cerr << "Cannot open file " << std::endl;
                return false;
        }

        std::vector<Kernel::Point_3> points;
        std::vector< std::vector<std::size_t> > polygons;
        if (!CGAL::read_OBJ(input, points, polygons))
        {
                std::cerr << "Error parsing the OFF file " << std::endl;
                return false;
        }
        //Mesh mesh;
        Polyhedron mesh;
        CGAL::Polygon_mesh_processing::orient_polygon_soup(points, polygons);
        CGAL::Polygon_mesh_processing::polygon_soup_to_polygon_mesh(points,
polygons, mesh);

        bool solved = solved =
CGAL::Polygon_mesh_processing::remove_self_intersections(mesh);

        if (!solved)
        {
                std::cout << "Some self-intersection could not be fixed" << 
std::endl;
                //return false;
        }

        std::ofstream ofs(filename);
        CGAL::print_polyhedron_wavefront(ofs, mesh);

        return true;
}

during this process the program generate the following warnings:

CGAL warning: check violation!
Expression : !"Returning no output. Filling hole with extra triangles is not
successful!"
File       :
C:\dev\CGAL-4.12\include\CGAL/Polygon_mesh_processing/internal/Hole_filling/Triangulate_hole_polyline.h
Line       : 1103
Explanation:
Refer to the bug-reporting instructions at
https://www.cgal.org/bug_report.html

The model is repaired after 971 seconds.

from:

Number self-intersections:..........290 (0.0618804 % of faces)
Number non manifold edge:...........0 (0 % of edges)
Number non manifold vertex:.........63 (0.026893 % of vertices)
IsCoherentlyOriented:...............False
IsOrientable:.......................False
 
to 

Number self-intersections:..........4 (0.000857012 % of faces)
Number non manifold edge:...........0 (0 % of edges)

IsCoherentlyOriented:...............True
IsOrientable:.......................True

Questions:
1. Is it possible to fix the problem related with the warnings?
2. How we can reduce the time of repairing?

Thanks in advance!
