<br>
Same memory drift with Scilab 5.5.2 and 6.0-a2 on win7_x64 is
observed.<br>
plot2d() is clearly involved, since further tests show that<br>

Memory linkage of plot2d() is not yet reported on bugzilla.

<pre wrap="">I'm running scilab-5.5.0 on Ubuntu 14.04.
When I run the attached script and then run "graphalot" for a while,
Scilab's memory usage climbs monotonically. What is actually getting
plotted doesn't seem to make a difference -- I just did the particular
plots seen there because it's fun.
I'm seeing this in a rather large, rather graphics-intensive script I'm
using. If I let the thing go unattended too long then Scilab slows to a
crawl and takes my computer with it -- I suspect that if I were willing
to wait for geologically significant amounts of time I could stop
Scilab, but I usually end up just cringing and whining, then resetting
the computer.
(I'm not sure what would happen in Windows, or if there's a better way,
under Linux, to make it not drag the rest of the world down. I just try
not to let the problem happen in the first place).
I searched the bugbase for it, but my ability to find good search terms
is usually far better in hindsight than actual use. So -- is this a
known bug, or should I file a bug report?
If it's known, has it been fixed? In what version?
Here's the script, in case file attachment doesn't work on the list:
function graphalot()
for n = 1:10000;
bob = rand(1, 5000, "n");
r = flts(bob, [%z^2 - 1; 0.5 * %z] / (%z^2 - 1.95*%z + 0.999));
scf(0);
drawlater();
clf;
plot2d(r');
ssz = stacksize();
xtitle(sprintf("iteration #%d, stack used %d", n, ssz(2)));
drawnow();
scf(1);
clf;
drawlater();
plot2d(r(1, :), r(2, :), frameflag = 3, rect = [-150, -150, 150,
150]);
drawnow();
end
endfunction
