[Dot] newrank causes "Warning: Unable to reclaim box space in spline routing for edge" error
Ported Issue from Mantis Original ID: 2597 Reported By: ball
SEVERITY: MAJOR Submitted: 2016-05-10 20:28:21
newrank under certain circumstances which I have been unable to predict causes dot to become very confused and unusable. I have tried hard to create a simple example that causes the error to no avail. I do have a complex example which if I remove some portion of which will pass. What is odd is I can remove different parts and it will pass, but there is no pattern I can discern.
STEPS TO REPRODUCE
Run my dot with dot -Tcanon or whatever.
One way to avoid the error is to comment out line 10 and 68, both of which merely define edges. Another way is to comment out line 85 which defines a cross-cluster rank. Removing a bunch of sub-clusters which aren't associated with any edges also seems to work for whatever reason.
I know of no work-around and as such I really need a solution to this problem!
