Steps to reproduce

The crash location as below, the function BRep_Tool::CurveOnSurface return null curve.

    // return the 1st curve 2d
    // and the 1st connection point
    if (sharp.Value(ic))
      curv2d1 = BRep_Tool::CurveOnSurface(TopoDS::Edge(Evive.Value(ic)),TopoDS::Face(Fvive.Value(ic,icplus)),
                                              u1bid,u2bid);
    else
      Calcul_C2dOnFace(CD.Value(ic),jf.Value(ic),i.Value(ic,icplus),curv2d1);
    p2d1 = curv2d1 ->Value(p.Value(ic,icplus));
