System Information
Win 7 64bit

Blender Version
Broken: 2.70 b66a954
Worked: (optional)

Adding translate node to a rendered layer causes bright out of gamut color bands. Also the translation effect doesn't redraw correctly, resulting in portions of the image wrapping around edges (even when wrap function is OFF).

Exact steps for others to reproduce the error
Create a layer with alpha, add translate node then send to mix node. Alpha seems to be included weather I want it or not. Viewer Displays large red Chunks (they change size when I change the chunk render size). Composite output has no red blocks but has bad wrap from translate node.

.blend included.blast_test.blend

Looks like there are several different issues here:

Render layer node doesn't return proper result outside the render resolution rect (@Jeroen-Bakker thought we fixed that by initializing colors beforehand? does render layer actually return undefined values?!)
Not a bug: In order to correctly overlay an alpha-image on top of the base you should use an Alpha-Over node, not a Mix node. See here blast_test2.blend

Seems that the result outside the render resolution is not set (as Lukas mentioned) This was not always the case, so we should fix it.

Sorry for the late reply.
