Package: graphviz
Version: 2.26.3-12
Severity: normal
The attached input file, also copied below, crashed dot:
$ dot < storyboard/dot-crashes-on-this.dot
Warning: DC was already in a rankset, ignored in cluster G
Warning: A was already in a rankset, ignored in cluster G
dot: position.c:136: dot_position: Assertion `rank(g, 2, nsiter2(g)) == 0'
failed.
Aborted (core dumped)
(Uncommenting the three commented-out lines turns the assertion failure
into a segmentation fault.) I haven't managed to compile 2.28 to test
whether the newer dot also fails on this input.
The file:
digraph G {
subgraph cluster_DC {
DC;
}
subgraph cluster_A {
2;
3;
A;
}
{rank=same;
