Summary0001396: Dot dies with "Error: trouble in init_rank"
Description






Hi...



Thanks for writing dot, it's an extremely handy tool.



The following dot file is output produced by an automated program analysis tool.
When given as input to "dot -Tps", dot crashes with the following output:
<CD>
Error: trouble in init_rank
    virtual 3
    virtual 1
    virtual 2

    virtual 1
    virtual 1
    50 2
    virtual 1
    virtual 1
    47 2
    virtual 1
Aborted
</CD>



I can reproduce the same behavior with versions 2.16, 2.20.2,
and the September 5 2.21 development snapshot.



Removing some of the edges of the graph often seems to help
(for example, all of the edges labeled "--").



In addition, when I attempted to submit this bug report using the
online WWW form, I received a "500 Internal Server Error" message.



Cheers,
Peter
