[Dot] Trouble in init_rank assertion
Ported Issue from Mantis Original ID: 2562 _Referenced Attachment is only available in the original Mantis DB_ Reported By: email@example.com
SEVERITY: CRASH Submitted: 2015-07-26 20:18:52
OS BUILD: 3.13.0-32-GENERI
PLATFORM: VIRTUALBOX VM
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
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.
