%%%--- Operating System, Graphics card ---
OSX mountain lion, [i have no plan]
Alternative:
Windows 7 Professional, nvidia geforce gtx ti 550
- Blender version with error, and version that worked ---
2.69 and it seems previous versions do also have this bug

- Short description of error ---

The Scale node doesn't work if you set it on 'render size' after putting it behind another scale node

- Steps for others to reproduce the error (preferably based on attached .blend file) ---

go to compositor
use nodes
add scale node
set scale node to something <0
add scale node, set it to render size
it woun't work%%%

%%%What exactly mans "it wouldn't work" ? From what i could see here it actually all works as intended.%%%

%%%This is not actually a bug, Scene/Render modes are just “absolute”, they do not use X/Y scale factors, so hidden them for those cases in r60545.

Apart from that, everything works as expected: as the first scale node outputs a picture which is already of the render size, the second one just does strictly nothing!%%%

Not sure if commenting on a "Resolved" issue is frowned upon, if so, I'm very sorry. I was just wondering if the issue still exists in 2.76b yet was not fully sussed out in the provided example. I am having issues with two Scale nodes connected in series where I'd expect the Absolute option to convert my image to an absolute pixel value. It appears that the "Absolute" scaling option is completely dependent on the input image, and it's output seems intrinsically linked to the scene's render Resolution. See these node setups:

http:*www.pasteall.org/pic/95307
This image will render a full grumpy cat just like the input image at 4000x3000.

http:*www.pasteall.org/pic/95308
This image will render a "canvas" at 4000x3000 with an 800x100 grumpy cat in the middle.

Is this operating as expected? I performed a test on 2.63a, and the Absolute option did not seem constrained to the Render size.
