relates to:

  • SR-377 Implement NSKeyed[Un]Archiver

Issue Description:

This is crashing for me on Linux:

func throwAnError() throws {
    throw NSError(domain: NSCocoaErrorDomain, code: 1234, userInfo: nil)
}

func errorCrasher() -> Void {
    do {
        try throwAnError()
    } catch let error {
        print("\(error)")
    }
}

Looks like this may not be Foundation-related.

@rjmccall, any ideas?

Probably something broken in the ErrorType representation on Linux, which is different because of the lack of need to interoperate with NSError. Joe Groff might see something obvious.
