Title: trouble in init_rank

Version: 1.8.4
System: *-*-
Severity: major
Problem:
I've seen this both on Windows 2000 on i386 with 1.8.4 and under Solaris 8 with 1.7.6.

With a fairly large graph (I can't really include it since it has data in it I shouldn't make public) I get errors like this:

[all node names, which were all unique, replaced by "n" since I guess it's all meaningless to you anyway]

My digraph has some cluster subgraphs, nested 2 deep, and when I get this error (removing the clustering on a particular top-level subgraph makes the error go away) some of the 2nd level subgraphs are put on top of each other.

What does this message mean? If you want the source for the graph, do you have a script which can replcae all the node names with arbitrary names n1,n2,etc.?

Thanks, David
