Dear Dr. Sebastien,

Sorry for late reply.

I have the following code which crashes when running the following line:
        Nef_polyhedron NP1(*P1);


The code is as follows:
void BoolObject3(char *op, char *file1,char *file2,char *outfile)
{
        Polyhedron *P1 = new Polyhedron, *P2 = new Polyhedron;
  std::ifstream stream1(file1);
  stream1 >> *P1;
  std::ifstream stream2(file2);
  stream2 >> *P2;

        Nef_polyhedron NP2(*P2);
        Nef_polyhedron NP1(*P1);
        switch(*op)
        {
                case '+': NP1 = NP1 + NP2;break;
                case '-': NP1 = NP1 - NP2;break;
                case '*': NP1 = NP1 * NP2;break;
                case '^': NP1 = NP1 ^ NP2;break;
                default:break;
        }
        NP1.convert_to_polyhedron(*P1);
        // output the polyhedron to OFF file
        std::ofstream log(outfile);
        log << *P1; 
}


The driver code is as follows:
BoolObject3("+", "slot.off","oblique.off","result.off");


The OFF files are as follows (sorry that I can't attach files).
