Title: trouble in init_rank yet again (still in 2.20.2)
Submitter: Reinier Post
Date: Fri Aug 22 04:05:21 2008
Subsys: Dot
Version: 2.20.2
System: x86-*-
Severity: major
Under Linux, I get: % dot -V dot - Graphviz version 2.20.2 (Thu Aug 21 15:40:01 UTC 2008) % dot -Tps Error: trouble in init_rank virtual 5 virtual 10 [...] virtual 1 virtual 1 Abort 6.014u 0.018s 0:06.05 99.5% 0+0k 32+0io 0pf+0w

Also tested, with the same results, on 2.8 (on Linux), and 2.18 (Windows XP).

Tested, successful ways to make the problem go away:
+ remove more arcs (this is probably not the minimum size at which the problem occurs but have already trimmed it down from the original)
+ rename the cluster_ prefixes to luster_ (i.e. remove clustering)
+ remove the empty arc labels (!)
