Missing MWE:
Polygon_2<K> ob;
ob.push_back(Point_2<K>(1, 1));
ob.push_back(Point_2<K>(1, 0));
ob.push_back(Point_2<K>(4, 0));
ob.push_back(Point_2<K>(4, 4));
ob.push_back(Point_2<K>(0, 4));
ob.push_back(Point_2<K>(0, 1));
Polygon_2<K> hole;
hole.push_back(Point_2<K>(2, 1));
hole.push_back(Point_2<K>(3, 1));
hole.push_back(Point_2<K>(3, 2));
hole.push_back(Point_2<K>(2, 2));
hole.push_back(Point_2<K>(2, 1.75));
hole.push_back(Point_2<K>(2, 1.25));
Polygon_2<K> new_poly;
new_poly.push_back(Point_2<K>(1, 1));
new_poly.push_back(Point_2<K>(2, 1));
new_poly.push_back(Point_2<K>(2, 2));
new_poly.push_back(Point_2<K>(1, 2));
{
Polygon_set_2<K> inter(ob);
inter.difference(hole);
inter.difference(new_poly);
}
and followup union before subtraction:
{
Polygon_set_2<K> hole_set(hole);
hole_set.join(new_poly);
Polygon_set_2<K> inter(ob);
inter.difference(hole_set);
}
