Where's the problem here? I think the problem is that there are two assignments to x with no intervening sequence point. Although the expression (x)^=3D(y) is _evaluated_ first, it doesn't mean that the resulting value is then assigned to x before the result of the expression (y)^=3D(x)^=3D(y) is; the compiler is free to do it the other way around.
