Is this reproducible on newer versions?
Any suggested workarounds?
STEPS TO REPRODUCE
digraph G {
ranksep=1;
overlap=false;
node [shape=box];
edge [fontsize=9];
root=TOP; TOP [label="\nbit_sink", peripheries=2, style=filled, shape=ellipse];
xs [label="xs\ngeneric_ev_sink"]; TOP -> xs [label=" Vddl VSS I-v I-e"];
xs__xb [label="xs/xb\nINV_2_"];
xs -> xs__xb [label=" Vddl VSS v e"];
}
ADDITIONAL INFORMATION
[north]
2.22? 2009? did you try a newer one?
otherwise we will have to wait for the invention of time
travel to go back to 2009 to correct the old version

Sorry, I'm at work on machines I don't have install priviliges for.
I'll try on a more recent one on my Mac when I get home.

If they installed devel packages on your machine you can build graphviz yourself.
Even if they didn't you can build local copies of all those libraries (I used to anyway)
but it's a bit time consuming. But the computer has a lot of free time so it's just running
autogen/configure and make install about 10 times.
[david]
When I try with a newer version:
twopi - graphviz version 2.26.3 (20100126.1600)
It doesn't crash, but the resulting graph (atteched pdf) is incomplete:
The root node TOP is missing entirely.
What does anyone else get?
[erg]
I can't reproduce the exact problem, but I do hit an assertion failure.
As a workaround, try changing overlap=false to overlap=prism.
It appears using overlap=false causes the node xs to be given the position
(nan,nan), but only if the node xs_xb is a box.
[david]
overlap=prsim isn't supported in 2.22.x (work machine)
Will try on my home Mac later, which has 2.26.3.
[erg]
Or try overlap=scale
