I see that too.
Don't know enough about nodes to know if its a bug or not.

Even in cycles you see a difference. I thing that the difference is by what is determined as the dead center of the pixel coordinate. (lower left verses precise center). But will need more testing (if this is the case) and discussion about what should be the correct implementation.
