|Summary||0001879: Bug using sub graphs|
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 ?
|Steps To Reproduce|
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?
> I take it the graph does not crash on Linux?
> What output do you get if you run dot -v?
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
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.
