Hello,

I have write a small package:

---------------------------------------------------
-- ads
---------------------------------------------------
package Image is

     type Color_T is record
         Red:   Integer;
         Green: Integer;
         Blue:  Integer;
     end record;

     type Image_T is array(Positive range <>, Positive range <>) of Color_T;

     procedure Fill(Image: in out Image_T; Color: Color_T);

end Image;

---------------------------------------------------
-- adb
---------------------------------------------------
package body Image is

procedure Fill(Image: in out Image_T; Color: Color_T) is
begin
      for x in Image'range(1) loop
          for y in Image'range(2) loop
              Image(x,y) := Color;
          end loop;
      end loop;
end Fill;

end Image;


---------------------------------------------------
-- test
---------------------------------------------------
with Image;
use Image;

procedure Test_Image is
     Image : Image_T(1..100, 1..100);
     FillColor : constant Color_T := (0, 0, 0);
begin
     Fill(Image, FillColor);
end Test_Image;


This program seems to work.
However when I increase the size of Image, I get a Segmentation fault.

Should I need to play with access type and allocation stuff ?

Thanks,

Olivier
