// Rustc displays a compilation error when it finds a `mod` (module)
// statement referencing a file that does not exist. However, a bug from 2019
// caused invalid `mod` statements to silently insert empty inline modules
// instead of showing an error if the invalid `mod` statement had been passed
// through standard input. This test checks that this bug does not make a resurgence.
// See https://github.com/rust-lang/rust/issues/65601
// NOTE: This is not a UI test, because the bug which this test
// is checking for is specifically tied to passing
// `mod unknown;` through standard input.
