I also find that this is fixed in the development branch which is about to become the 4.0. release.  I am marking the bug as fixed.  It can be re-opened if the original reporter can reproduce the problem after the 4.0. release.

@Philip Thanks for the link, I tried several of the font options,

export GS_OPTIONS='-dNONATIVEFONTMAP -sSUBSTFONT=Helvetica'
-FHelvetica in print command

but they didn't work, the second actually made it worse. I tried different fonts, but that didn't work either.

@Mike I don't know how to test from development tree... but I tried graphics_toolkit("gnuplot") and it works, thanks!

Thanks for your bug report. This looks to me to be limited to the FLTK toolkit, and also looks to be fixed in the current development version of Octave.

Specifically, your example gives me the behavior you describe using 3.8.2 and on the gui-release branch, but not on the current default branch. If you are able to test Octave from the development tree, can you confirm that the problem you are seeing is fixed? Can you also confirm that switching to graphics_toolkit("gnuplot") fixes it even in 3.8.2?

I have a severe problem when I try to run the following script:

close all

Mfun= @(b,B) (exp(b).*sinh(b.*B))...
    ./sqrt(exp(2*b).*cosh(b.*B).*cosh(b.*B)-2*sinh(2*b));

bvec   = 0:0.02:2;
BVEC   = 0:0.1:10;
M_L = zeros(length(bvec),length(BVEC));
for i=1:length(bvec)
  for j=1:length(BVEC)
    M_L(i,j) = Mfun(bvec(i),BVEC(j));
  end
end

surf(bvec,BVEC,M_L.')

print('test.eps','-depsc')

Everything goes fine until the print command. When I watch my ressource usage with "top", the octave %MEM usage goes up until about 68% (almost 3 GB) and then my PC is dead. Only thing I can do is to press the Power button to shut it off.

If I react quickly enough on the command line, I can cancel octave with Ctrl-C Ctrl-C Ctrl-C. If I use "saveas" from the menu instead of print(...), I cannot cancel octave. In any way, I don't get my plot as an eps file.

I don't want octave to be able to somehow use up all of my memory.

I use openSUSE 13.1, octave 3.8.2
