Summary0000438: missing edge
Description



There are four edges between nodes 6 and 9 in the source:
(two 6--9 and two 9--6)
but only three show up in -Tpng.



If the graph is converted to a digraph then one edge has become
bidirectional with arrows at both ends
Steps To Reproduce

graph net_state {
  node [shape=box]
  1 [label = "nATLNGATL"]
  2 [label = "nCHCGILCLW60"]
  3 [label = "nDLLSTXTL"]

  8 -- 6 [_utilization = 0, _threshold = 0, _dmds = 0];

Comments :
[erg] Here is a reduced graph exhibiting the problem:
<CD>
graph net_state {
  5
  6
  5 -- 9
  6 -- 9
  9 -- 6
  6 -- 9
  9 -- 6
}
</CD>
The bug goes back at least to 1.9.
