Title: graphviz is unable to render a dot file
Submitter: Daniel Le Berre

Subsys: Dot
Version: 2.20.2
System: *-*-
Severity: critical
I got a program that generates automatically a dot file.

It works fine for toy problems (22 nodes).

It looks like graphviz gives up on bigger graphs (376 nodes).

dotty.lefty: giving up on dot
dotty.lefty: graph that causes dot
dotty.lefty: to fail has been saved in file
dotty.lefty: please fill out a bug report at

Input file:
[erg] The combination of many edge labels and constraint=false appears to cause many problems: trouble in init_rank or non-touching boxes in spline routing -- depending on which attributes are commented out. A simpler version of the input file is here.
