[Octave-bug-tracker] [bug #47468] ones() is able to create array with number of elements above sizemax

[anonymous]

Follow-up Comment #3, bug #47468 (project octave):

I can confirm this problem with octave 3.8.2 (Ubuntu Linux 12.04) too for
zeros function.

When I do a fresh start of octave with experimental forced GUI I can generate


-----------------------
test = zeros(18059);
-----------------------


without errors.

When I try to add some other variables to that, lets say


------------------------
n=0;
while(1)
  n++;
  dump{n} = zeros();
endwhile
------------------------


it is even possible to add a few arrays with small size (~10 - 50 square
arrays).

.

Then I clear everything and repeat the steps but

even the 18059*18059 zeros aren't working.

Add some point even arrays with 



test = zeros(floor(sqrt(sizemax/8.0)-1.0));



won't work.


Is there no possiblity to check how much unfragmented memory is still
available for arrays in octave by a 



system('some script')




My System Specs (lshw -short) and Linux distro is...
