Can you try reproducing with a more recent compiler, such as a snapshot toolchain? https://swift.org/download/#snapshots

I tried compiling the following program with a master compiler @ 50c0534206481bb7eebe1b4639f590a7eb5c07c0 and it gave me a compiler error instead of a crash.

import AppKit
let _ = NSPasteboard().readObjects(forClasses: [URL.self])
