[Dot] rankdir="LR" causes various crashes and drawing errors
Ported Issue from Mantis Original ID: 1435 Reported By: Nick Wimpney
SEVERITY: MAJOR Submitted: 2008-10-08 05:00:00
OS: X86-DEBIAN SID
VERSION: 2.20.2
DESCRIPTION
with rankdir set to "LR", on some large graphs I got an "Aborted" error with no other info. On a small graph it completes, but connections in the same rank aren't drawn.
STEPS TO REPRODUCE
graph testgraph {
rankdir="LR";
A1 -- A2;
A1 -- B1;
A2 -- B2;
{ rank = min; A1 A2 }
{ rank = same; B1 B2 }
}
ADDITIONAL INFORMATION
There seem to be several other rankdir "LR" bugs open. They're probably all related, but most are overcomplicating the circumstances.
