Summary0001878: Trouble in init_rank
Description



The input graph crashes at



<CD>
   /home/ek/dev/src/lib/libgv/mincross.c:1190
1190 ND_order(v) = i + (GD_rank(g)[r].v - GD_rank(Root)[r].v);
</CD>



The \<A HREF="b1948a.gv"\>shortened version\</A\> hits an assertion failure. If the rankdir
line is removed, one gets



<CD>
Error: trouble in init_rank
        virtual 2
        virtual 2
        virtual 1
        virtual 1
        n34 1
        n62 1
Bus error
</CD>
Additional Information

[erg] Part of the problem relates to the separate non-cluster subgraphs.
Semantically, one should be able to replace them with

<CD>
subgraph sg {
            graph [rank=same];
            n1
            n113
            n43
            n91 -> n28
}
</CD>

but if this is done, the problem goes away.
TagsNo tags attached.
