Issue Description:

The following example results in a Segmentation fault: 11 when built with Xcode 9.3 Beta 3, Swift 4.1 and Optimization Level set to -O or -Osize. A sample project can be found here.

import Foundation
import RealmSwift

class Foo: Object {
    let bars = LinkingObjects(fromType: Bar.self, property: "foo")
}

class Bar: Object {
    @objc dynamic var foo: Foo?
    @objc dynamic var string: String?
}

extension Foo {
    var crash: Bool {
        return Array(bars.filter { $0.string == nil }).isEmpty // --> segmentation fault 11
        // return bars.filter { $0.string == nil }.isEmpty --> does not crash
    }
}
