Title: neato and splines fails
Submitter: Marco Wobben
Date: Wed Mar 13 04:16:50 2002
Subsys: Neato
Version: 18
System: x86-Other-win2000
Severity: major
Problem:
Once neato is used with "splines=true" the program calculates forever as soon as more nodes/edges are added. And very soon no splines are plotted.

C:Program FilesATTGraphvizbinneato.exe -Tpng sample.dot -o sample.png
Input: 

digraph SourceDependencies {
    ratio=auto; node[fontname=Tahoma, fontsize=10]; overlap=false;
    nodesep=2; splines=true;
    edge [len=2];
  subgraph cluster0 {
    node [style=filled, color=limegreen];
    style=filled;
    color=linen;
    a -> b;
    a -> c;
    a -> d;
    b -> c;
    d -> c;
    a -> e;
    d -> e;
    d -> b;
    e -> c;
    f -> c;
    g -> a;
  }
}
Comments:
removing the line "g -> a;" will no longer let neato calculate forever.

[erg] No declaration of drand48() in splines.c, producing very strange numbers.
