A bug of AutoreleasingUnsafeMutablePointer compiling

AutoreleasingUnsafeMutablePointer.swift

import UIKit

class ViewController: UIViewController {
    
    struct OneStruct {
    }
    
    class OneClass {
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        
        
        // compile failed
        var oneStruct: OneStruct?
        test(&oneStruct)
        assert(oneStruct != nil)
        
        // compile success and run success
//        var oneClass: OneClass?
//        test2(&oneClass)
//        assert(oneClass != nil)
    }
    
    func test(_ p: AutoreleasingUnsafeMutablePointer<OneStruct?>) {
        p.pointee = OneStruct()
    }
    
    
    func test2(_ p: AutoreleasingUnsafeMutablePointer<OneClass?>) {
        p.pointee = OneClass()
