0001621: Assertion `(g)->u.rank[r].n <= (g)->u.rank[r].an' failed.




By drawing a certain graph, i receive the



"dot: mincross.c:846: install_in_rank: Assertion `(g)->u.rank[r].n <= (g)->u.rank[r].an' failed."



error, whilst laying out the same graph without subgraphs (some nodes are expanded into subgraphs) causes no problems. I attached the text file for debugging reasons.
No tags attached.

I'm having the same problem. I'll upload my dot which is a lot simpler than the OP's.
