Details:

Running this script for about 1500 iterations uses up all my 4 gigabytes of
memory so my system starts to swap and it becomes almost inresponsive:


i=0
do
 i=i+1;disp(i) 
 data=rand(100000,1);
 plot(data);drawnow;
until false


Also if stopping early, used memory is never released, even after the figure
is closed or cleared.

When trying to stop the loop with multiple ctrl-C, Octave crashes with

+verabtim+
^C^C^C^C^Cterminate called after throwing an instance of
'octave::interrupt_exception'
fatal: caught signal Abgebrochen -- stopping myself...
octave exited with signal 6


No such problem in 4.1.0.
