Package: octave
Version: 3.8.1-1+b1
Severity: normal

I found this bug first in the normal packaged version of Octave in
Debian. The attached stack traces were created with a local build
without optimization to get meaningful stack traces. The code orginates
from matlab2tikz's test suite.

================================================================
$ cat mesatest.m 
x = -pi:pi/10:pi;
y = tan(sin(x)) - sin(tan(x));
y(3) = NaN;
y(7) = Inf;
y(11) = -Inf;
plot(x,y,'--o', 'Color', [0.6,0.2,0.0], ...
                'LineWidth', 1*360/127,...
                'MarkerEdgeColor','k',...
                'MarkerFaceColor',[0.3,0.1,0.0],...
                'MarkerSize', 5*360/127 );
================================================================

$ gdb -q  --args /usr/bin/octave --quiet --persist --eval "mesatest"

done.

I am filing the bug right now in the hope that someone has an idea on
how to continue with this - I have no clue whatsoever about Mesa.

I can no longer reproduce this issue with the current mesa in unstable
(10.4.2 at the time of writing), so I am closing this bug.

Thanks Mike for helping with it and sorry for the long delay - I just
overlooked your email in October.
