Neither do I know of any evidence suggesting that software correction is to blame in this regard.

On large prints with my 14-45, I can see large pixel 'aliasing' in details near the corners after a standard global USM pass - a problem that is not present throughout the rest of the image. I use a layer mask to remove this (eliminate USM at the cost of corner sharpness), but it is a problem unique to my software corrected lenses.

The magenta cast that you observe comes as news to me Chez, although I have the same camera and lens and sometimes push shadows in PP.

It isn't really from pushing the shadows, you see it with a strong s-curve, or when you are pulling exposures in really bright/contrasty locations. I have only ever seen this on snow however. Stitching is when it becomes a real problem.
