// When an empty output file is passed to rustc, the ensuing error message
// should be clear. However, calling file_stem on an empty path returns None,
// which, when unwrapped, causes a panic, stopping execution of rustc
// and printing an obscure message instead of reaching the helpful
// error message. This test checks that the panic does not occur.
// See https://github.com/rust-lang/rust/pull/26199
