// Invalid paths passed to rustc used to cause internal compilation errors
// alongside an obscure error message. This was turned into a standard error,
// and this test checks that the cleaner error message is printed instead.
// See https://github.com/rust-lang/rust/issues/13517

// already present by default in UI testing.
