          Hardware: PC

BUG DESCRIPTION:
----------------

Hi, 

I'm reopening bug #11348 because the problem is still there (and because my previous 
remark may not have been noticed). 

Alain



ERROR LOG:
----------
NONE



HOW TO REPRODUCE THE BUG:
-------------------------

// (based on Guillaume's example - see bug #11348): 

// plot N random rectangles
function [t] = TEST(N)
  f = scf(); 
  f.immediate_drawing = "off"; 
  tic(); 
  xrects(rand(4,N),ones(1,N)); 
  t = toc(); 
  f.immediate_drawing = "on"; 
endfunction


// --- case 1 --- 
TEST(10000)

// 5.3.3: 0.03 s
// 5.5.2: 6.3 s  => MUCH MUCH SLOWER (time x100 or more)


// --- case 2 ---
TEST(100000)

// 5.3.3: 0.2 s
// 5.5.2: *** SCILAB CRASHES *** (all windows disappear from the screen, even with stacksize("max"))!
