Summary0001084: Graph which crashes neato
Description



The following graph reliably crashes neato:



On Windows XP SP2, Graphviz versions 2.6 and 2.8.



Taking the / out of the labels seems to stop the crash, as does removing
the overlap setting, but I really want both these to stay as the graph
is being automatically generated.



Does anyone have suggestions for anything I'm doing wrong?
Steps To Reproduce

digraph G {
overlap=false;
  "00000661";
  "000006c0" [shape=record,label="ats/UserRequirements"];
  "000006c1"
[shape=record,label="/EasyStart/Requirements/SystemRequirements"];
   "00000661" -> "000006c0";
   "000006c0" -> "000006c1";
   "000006c0" -> "000006c0";
}

Additional Information

[erg] I believe the problem is related to a strange bug in the Voronoi
code. In any case, running neato -n on
\<A HREF="b906.dot"\>this input\</A\> causes a SIGFPE on linux. The reason
the problem doesn't occur originally on Linux is that it starts with
a different layout (due to the RNG), so the exact values needed aren't
there. The crash in Windows occurs later, but Windows uses non-trapping
semantics on floating point exceptions, so it's only later when things
fall apart.
