Here's the fragment of source from rebuild_vlists() conc.c:
190: for (r = GD_minrank(g); r <= GD_maxrank(g); r++) {
191: lead = GD_rankleader(g)[r];
192: if(ND_rank(g->root)[r].v[ND_order(lead)] != lead)
193: abort();
194: GD_rank(g)[r].v = ND_rank(g->root)[r].v + GD_rankleader(g)[r]->u.order;
195: maxi = -1;
and here is the input. I am sorry I was not able to reduce the test
case further. It started as 7000 line file, so I think I deserve
a medal for even managing to reduce it this much :-)
