Summary0002443: Segfault laying out graph with 7 subgraphs - affects dot, gvedit, layout library
Descriptiondot (and gvedit, and the layout library) crash when trying to lay out the attached dot file, which includes 7 small cluster subgraphs. If I manually delete the seven clusters from the file, it lays out fine. Other graphs using this general approach (only put the cluster nodes explicitly in the subgraph, put all arcs at top level) lay out fine.

Deleting only the last cluster crashes the same way as the original file.
Deleting the final 2 clusters (leaving 5) creates a layout, but produces the message
Warning: Unable to reclaim box space in spline routing for edge "PARTNER_FOO" -> "L1_IN". Something is probably seriously wrong.

Deleting the final 3 clusters (leaving 4) crashes with a "reclaim box space" message; deleting 4 clusters (leaving 3) runs but produces 2 "reclaim box space" messages; leaving 2 clusters runs without complaint; leaving 1 cluster crashes with 2 "reclaim box space" messages; leaving 0 clusters runs without complaint.

One workaround is to use newrank=true when running dot.

Thanks - newrank=true does seem to avoid the crashes I've observed so far.
