Details:

In MATLAB I frequently used a construct like this:


figure(1)
while isfigure(1)
 data=rand(100,1);
 plot(data);
 drawnow
 pause(1)
end

 
Closing the figure window should terminate the loop.

But in Octave clicking the close button seems to have no effect.

But afterwards, when terminating the loop with Ctrl-C, Octave immediately
crashes with a segfault.
