Summary0001888: Constraint / Subgraph
Description



There might be a possible bug when a "box" is part of two unconstrained
relations and one relation(edge) leads into another subgraph,
the edge between the two subgraphs is doubled.






Here are two simple examples:



<CD>
==================================================================
===[ incorrect ]==================================================
==================================================================
Digraph g {



  node [shape=box];



subgraph cluster1 {
  label="X";
  A;
  B;
  C;
}
subgraph cluster0 {
  label="Y";
  Q;
}
  C->B [constraint=false];
  A->B [constraint=false];
  A->Q [constraint=false];
}



==================================================================
===[ correct ]====================================================
==================================================================



Digraph g {



  node [shape=box];



subgraph cluster1 {
  label="X";
  A;
  B;
  C;
}
subgraph cluster0 {
  label="Y";
  Q;
}
  C->B [constraint=false];
  A->B;
  A->Q [constraint=false];
}
</CD>



I reported that possible bug once before, but now I figured out a
possible reason.



Hope this helps.
