Are you sure that the vertex handle in question is still a vertex
of the triangulation.

Say when you do this:

std::list<Vertex_handle> vertices;

Vertex_handle vh = dt.insert(Point_2(0,0));

vertices.push_back(vh);

dt.remove_vertex(vertices.front());

dt.incident_vertices(vh);

this will crash.

It's to expect that in debug modes some things work that don't in release 
mode.

You haven't upladed anything. If I look at it depends on the code 
size/complexity
