Summary0001879: Bug using sub graphs

Dear Sirs.

I've been having a quite unfamiliar problem using graphviz. I'm building an application
that uses graphviz to design some process models.

When i started to use subgraphs, sometimes graphviz crashes without any "possible debug" message.

I've trying to figure out what the problem is, but what i found out is that if
i just delete some of the lines of my deployed dot file, without any known logic, it works, so i can't find any logic
concerning this error. I've tried to update to your last version but the problem persists.

Is it possible to try a help me on this ?

Best regards,

Carlos Liborio
Steps To Reproduce

Additional Information
Please keep my input private.

Carlos asks for his graph to be kept private. Could you remove it from the bug system, please?


I worked your graph a little, so that at least it generates something:
    - I moved all edge declarations outside of the clusters.
    - I removed a number of duplicate node declarations.
    - I moved a few nodes into, or out of, clusters where it seemed to make sense, but I'm sure I got it wrong.
    - I added null labels to Initialization and End, since the fixed size leaves no room for the text.

There doesn't seem to be a good flow to your graph for a nice looking directed layout with dot. Hopefully this is something you can fix now that you can see the output.

I tried using the "fdp" layout engine, which also supports clusters, but the result doesn't look any better.

Hope this helps?

No, the original crashes on Linux. It crashes with:

    Warning: node 'Initialization', graph 'G' size too small for label
    Warning: node 'End', graph 'G' size too small for label
    Error: trouble in init_rank
        virtual 1
        virtual 3
    Aborted (core dumped)

Then this is another case of the "trouble in init_rank" bug.
The only question then is why he didn't get the error message when
he ran dot.
