Summary

0023860: Bad memory access intersecting two nearly coincident cylindrical faces

Description

Executing the following code results in an access violation in Release on Windows and MacOS. It throws an exception in debug.

Steps To Reproduce

        gp_Ax3 axes1(gp_Pnt(1031.3339148728076, -113.25868616662650, 56.152387686082520),
                        gp_Dir(-0.86602540378443815, 0.50000000000000089, 0.00000000000000000),
                        gp_Dir(-0.50000000000000089, -0.86602540378443815, 0.00000000000000000));
        Handle(Geom_CylindricalSurface) surface1(new Geom_CylindricalSurface(axes1, 76.499999999999986));
        gp_Ax3 axes2(gp_Pnt(1017.0706583606553, -103.24955863669388, 56.152387686082548),
                        gp_Dir(0.86602540378443915, -0.49999999999999933, 0.00000000000000000),
                        gp_Dir(0.49999999999999933, 0.86602540378443915, 0.00000000000000000));
        Handle(Geom_CylindricalSurface) surface2(new Geom_CylindricalSurface(axes2, 76.499999999999986));
        BRep_Builder builder;
        TopoDS_Face face1;
        TopoDS_Face face2;
        builder.MakeFace(face1, surface1, Precision::Confusion());
        builder.MakeFace(face2, surface2, Precision::Confusion());
        IntTools_FaceFace intersection;
        intersection.SetParameters(false, true, true, Precision::Confusion());
        intersection.Perform(face1, face2);
