|0002562||graphviz||Dot||public||2015-07-26 15:18||2015-07-28 11:33|
|Platform||VirtualBox VM||OS||Ubuntu||OS Version||3.13.0-32-generi|
|Summary||0002562: Trouble in init_rank assertion|
|Description||When I try to render the attached graph I get:|
'Error: trouble in init_rank',
eventually followed by:
'dot: maze.c:315: chkSgraph: Assertion `np->cells' failed.'
Dot then dumps core from the unhandled assertion.
|Steps To Reproduce||cat test2.dot | /usr/bin/dot -Tpdf -o test2.pdf|
|Additional Information||If the 'rank=sink;' statement on line 170 is commented out, then this renders with no problem. |
Is there some way to get around this issue, by some settings or something similar? If I comment out this line then the nodes within the block don't render nicely.
Also, my graphs in general are auto-generated so it would be desirable to have a general solution and not have to hand tune each one.

|I found that if I add 'constraint="False" to all of the edges which reference the nodes in the block with 'rank=sink;' at line 170, then it doesn't crash.|
I agree this is a bug, but it's very brave to mix concentrate=true, splines=ortho, packmode, ranksep, nodesep, and a bunch of other options we probably never tried in the lab.
I wish our code was more robust or did better self-checking.
