Details:

>From bug https://savannah.gnu.org/bugs/?49756 is a script that causes a
gnuplot failure:


graphics_toolkit gnuplot
figure(1),clf
im=uint8(rand(100,100)*255);
imshow(im)
hold on;
xs=[0 0 1 1 0];ys=[0 1 1 0 0];
xoff=xs-0.5;yoff=ys-0.5;
offset=50;
plot(xs+offset,ys+offset,'rx')
plot(xoff*0.75+0.5+offset,yoff*0.75+0.5+offset,'b')
hold off;


The image draws fine, but then the plot following "hold on" fails.
