Summary0000998: CVS build of neato dies with "caught SIGFPE e" on even the simplest graph

Just try running neato on the input file below.
It doesn't appear to matter what specifically the input is, it always

I'm upgrading from 1.14 to 2.2, building from the CVS sources. I'm really
interested in the TopFish visualization technique, but also in just
laying out small graphs (up to 100 nodes), to understand the protein
interaction network in humans. GraphViz is still the best tool
I've come across for quickly laying out that kind of graph,
and allowing me to customization the decoration according to
various kinds of biological information.
I've been using graphviz for a number
of years (Stephen North even wrote us a letter of support for a grant
application a year or two back - that was in connection with
using graphviz to visualize multigraphs).
I'd be really glad to have some kind of fix.

I noticed from reading the earlier bug reports, that I'm not the only
one who encountered this problem. Like the previous user (bug 0000595),
I'm using gcc 2.95.x (x=4 in my case), I'm not really interested in upgrading,
so looking for a fix.

Thanks in advance,

Steps To Reproduce

graph g {
two -- one
Additional Information

[north] Frank: topfish (er, topview) is not in graphviz, but we would
like to find academic partners who are interested in working
with it. We can issue university ("non-commercial) licenses
but it's not open source.

With gcc problems, you might try compiling everything
without -O and if that does the trick, then figure out which
file in particular tickles the gcc bug. I can't remember the
likely suspects any more (at least for neato; in dot it was
generally the spline fitting functions).
It's been a long time since I followed the area but there used
to be alternatives to gcc, such as lcc and of course if you
want to spend real money there's Comeau, Intel, etc.
