But pointer are always a source of errors.
Only use them when it's unavoidable.
If you can do the same without pointers then don't use them. ;-)
Of course, if you just use pointers because others do, indeed they might
be...

Could it be that you do something else with "edge_list" before the
assignment?
Keep in mind that "edge_list" is a dynamic array and therefore a point

v2: PVertex;
end;
I have assigned a value to a vertex variable. In my code I have an
array of TEdge. When
