Im try to implement diagnostic algorithms for not valid mesh(non-manifold
vertices, non-manifold edges, etc) I know that there are functions that let
me repair these errors. I don't want to repair it. What I want to only do it
is to Diagnostic a mesh with a particular error (Not repairĀ  it).

I try to use CGAL/Surface_mesh.h

https://doc.cgal.org/latest/Surface_mesh/index.html#title13

in order to iterate through all structure data and find these errors but it
does not work if the mesh has errors.

how i can iterate through haldedges, vertices, points of the invalid mesh in
order to find this errors? (Not repairing methods please)

For example: cube_e.off has non manifold vertex

cube_e.off
<http://cgal-discuss.949826.n4.nabble.com/file/t375958/cube_e.off>

if the file is process with this example it does not work:
