Details:

I can produce a segfault on versions 3.4.3, 3.5.90 and Mercurial sources of
Octave.  Here is the command that is run from the installation:

make[3]: Entering directory
`/home/melrobin/octave/current_octave/octave/doc/interpreter'
../../run-octave -f -q -H -p . --eval "geometryimages ('voronoi', 'eps');"

Here are the results:
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
make[3]: *** [voronoi.eps] Segmentation fault

This was for a build on Mercurial sources, but I am able to reproduce this for
3.4.3 and 3.5.90:
octave:1> version
ans = 3.4.3
octave:2> geometryimages ('voronoi', 'eps');
warning: X11 DISPLAY environment variable not set
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault
address@hidden interpreter]$

and

octave:1> version
ans = 3.5.90
octave:2> geometryimages('voronoi','eps');
panic: Segmentation fault -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Segmentation fault
address@hidden interpreter]$

The octave-core file seems pretty empty save for a variable called ans.

I can try to troubleshoot some more, but don't really know where to go.  It
seems to be raised as a bug because the problem occurs in multiple versions.
