Summary0002026: Simple hierarchical graph crashes dot
Description



We are producing hierarchical graphs, but
dot seems to crash rendering them for a large range of parameters.
The dot command is



dot -Teps -oprimes.eps primes.dot



gdb tells that the crash is triggered in triangulate()
which is passed an invalid polygon.



I could not find a workaround, tuning parameters (letter sizes...)
sometimes makes the bug disappear.
Additional Information

[erg]
If you comment out the last edge, the problem goes away. However, the
resulting output shows that the second edge, from keysOut to stamps,
is broken. Only by removing all port names and compass points do you
get a good edge. It almost appears that some node translation is not
being done.

I have attached a smaller \<A HREF="b2111a.gv"\>example\</A\> with
\<A HREF="b2111.png"\>output\</A\>. The cluster is necessary to cause the
problem.
