[Dot] Trouble in init_rank assertion #147

Open GadgetSteve opened 8 years ago

GadgetSteve commented 8 years ago

Ported Issue from Mantis Original ID: 2562 _Referenced Attachment is only available in the original Mantis DB_ Reported By: amorrissett@earthlink.net

SEVERITY: CRASH Submitted: 2015-07-26 20:18:52

OS: UBUNTU

OS BUILD: 3.13.0-32-GENERI

PLATFORM: VIRTUALBOX VM

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[1]' 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.

Jeremy,

Graphviz development has moved to, https://gitlab.com/graphviz/graphviz

Please create a new issue, or update an exusting issue, there

Please be sure to include a test case. History says that this is probably multiple problems with similar symptoms.

The code on github is no longer maintained or current.
