|Summary||0002231: Crash from use of nslimit|
When nslimit is used, it is possible that some nodes may still overlap or that the solution is degenerate. This can cause serious problems during spline routing as that code assumes no node overlap, in which case dot may crash. Or spline routing may run forever.
As a second problem, there is the question as to why it is necessary to set nslimit. This is a "bad" graph in that it is very long with many very long edges, so the dummy node blowup is large. But it is still hard to believe that network simplex shouldn't be able to handle it.
|Steps To Reproduce||dot -v -Gnslimit=10 -Gnslimit1=10 -Tpdf -o lorentz__cfg.pdf lorentz__cfg.dot|
|Additional Information||If nslimit is used, it might be good to check for overlap, or perform a small|
x adjustment to remove them.

On my MacPro with Snow Leopard, lorentz__cfg.dot appears to never stop. The lore2.dot version is the same but with half the edges removed. Here I get a crash
as the pathplanner attempts to allocate more memory.
