Title: Crash of dot, with this graph
Submitter: Torsten Will
Date: Thu Jul 27 04:01:35 2006
Subsys: Dot
Version: dot version 2.6 (Sun Aug 28 13:14:52 UTC 2005)
System: *-*-*
Severity: major
Problem:
dot crashes, lefty only display a black canvas. the crash seems to be in dot.exe itself, not in a windows dll. the dot-file is auto-generated and quite complex, alas.

Here is a similar input which does not crash.
Input file: b983.dot
Comments:
[ellson] Also fails on latest CVS version on linux. Looks like a cluster problem.
