  • SR-2773 function abnormally releasing instance.

Issue Description:

I get a Bad Access with following code using Xcode 8.1 beta (8T46g). I think because the path is released too early.

import Cocoa

public func with<T>(_ item: T, update: (inout T) throws -> Void) rethrows -> T {
    var this = item;
    try update(&this);
    return this
}

let path = with(CGMutablePath()) { // <-- Bad Access
    $0.move(to: CGPoint(x: 0, y: 0))
    $0.addLine(to: CGPoint(x: 100, y: 100))
}
