[Gmsh] Help: Segmentation Fault

[Chaman Singh Verma]

Hello,

I get segmentation fault while doing surface meshing. After debugging I
found the location of the
problem but don't know why it should happen.


The problem is with EdgeSwapping module. The problem starts  from

void BDS_Mesh::del_edge(BDS_Edge *e)
{
  e->p1->del(e);
  e->p2->del(e);
  e->deleted = true;
}

and in the BDS.h file ( In the BDS_Point ) class

inline void del(BDS_Edge *e)
  {
    std::list<BDS_Edge*>::iterator it = edges.begin();
    std::list<BDS_Edge*>::iterator ite = edges.end();

    while(it != ite){
      cout << " EDGE IS " << *it << endl;
      if(*it == e){
        edges.erase(it);
        break;
      }
      ++it;
    }

I notice that in the second function for some point in the edgelist, some
edge is NULL and
that creates the segmenation fault. Here is the output:

 EDGE IS 0x1734130
 EDGE IS 0x7f9a25875a60
 EDGE IS 0
Segmentation fault

I fail to guess the cases where a point refering to a NULL edge ? Can
someone give some hints
to resolve this problem ?


Thanks.
