  • SR-1512 Assertion failure: "Already marked as a fixed binding" when implementing index(_:offsetBy:limit:)

Issue Description:

Something along these lines will crash the compiler. Same in Playground.

import UIKit
let image = UIImage()
let bytes = image.cgImage?.height ?? 0 * image.cgImage?.bytesPerRow ?? 0

I'm at Xcode 8.
