Dear Sebastien,

At least for the example trc1.off - trc2.off, the assertions bellow seem to
fail:

Nef_3\include\CGAL\Nef_3\polygon_mesh_to_nef_3.h

line 263, 264
CGAL_assertion(ss_circle.has_on(sp));
CGAL_assertion(ss_circle.has_on(sv_prev->point()));

line 294, 295, 296
CGAL_assertion(ss_plane.has_on(sv_prev->point()));
CGAL_assertion(ss_circle.has_on(sp_0));
CGAL_assertion(ss_circle.has_on(sv_prev->point()));


Nef_S2\include\CGAL\Nef_S2\Sphere_direction.h

line 105
CGAL_assertion(d1.has_on(p) && d2.has_on(p) && d3.has_on(p));


Nef_S2\include\CGAL\Nef_S2\Sphere_segment.h

line 61
CGAL_assertion(c.has_on(p1)&&c.has_on(p2));


In Release mode, the subtraction works fine for the truncated right cone
example.

thanks,

S Dobashi
