    _______________________________________________________

Details:

I've started seeing segfaults at exit after using the Qt and Fltk toolkits.
Sometimes the Fltk toolkit will fail outright (changeset:
22193:e35866e6a2e0):

sebald@ ~/octave/gnuplot_bug48664 $
/usr/local/src/octave/octave/build1/run-octave --no-gui --silent
octave:1> graphics_toolkit ('fltk')
octave:2> demo('image',1)
image example 1:
clf;
colormap (jet (21));
img = 1 ./ hilb (11);
x = y = -5:5;
subplot (2,2,1);
h = image (x, y, img);
ylabel ("limits = [-5.5, 5.5]");
title ("image (x, y, img)");
subplot (2,2,2);
h = image (-x, y, img);
title ("image (-x, y, img)");
subplot (2,2,3);
h = image (x, -y, img);
title ("image (x, -y, img)");
ylabel ("limits = [-5.5, 5.5]");
subplot (2,2,4);
h = image (-x, -y, img);
title ("image (-x, -y, img)");

panic: Segmentation fault -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
Segmentation fault

I've gone back two or three changesets and the segfaults still occur at exit.
