> Almost everywhere equality is an equivalence relation and the derivative of the Cantor function is in the same equivalence class as the 0 function. And a function in that equivalence class will have an integral that is equal to a constant function on all intervals where that function is defined. If you also integrate over intervals where the function is only defined almost everywhere, all bets are off.
