Hi,

I get a weird segmentation fault and I really don't know why. Here is my 
code:

if (triangulation_.is_valid(currCell))
{
    for (int k = 0; k < 4; k++)
        cellsToProcess.push(currCell->neighbor(k)); // when accessing 
neighbor -> segfault
}

where triangulation_ is a 
CGAL::Triangulation_3<CGAL::Exact_predicates_exact_constructions_kernel, 
Tds_info>. and currCell is a Cell_handle.

I'm checking the validity of currCell, so the neighbors should exist, right?

Does someone have an idea why that could happen or how to check the 
validity of the neighbors  before accessing it in another way?

Thomas
