  • SR-10648 Linker fails to link open method that was previously internal

Issue Description:

The following should produce a compiler error, but instead it produces an "Abort trap: 6" and the initial error starts off with

Global is external, but doesn't have external or weak linkage!
%swift.method_descriptor* @"$s7Shopify4BaseC8function33_72119E9B637C621F6419FCE57445EE94LLyyFTq"
<unknown>:0: error: fatal error encountered during compilation; please file a bug report with your project and the crash log
<unknown>:0: note: Broken module found, compilation aborted!

In File1.swift

class Base {
  fileprivate func function() { }
}

class Sub1: Base {
  override func function() { }
}

File2.swift

final class Sub2: Sub1 {
  override func function() { }
}
