// Passing invalid files to -Z ls (which lists the symbols
// defined by a library crate) used to cause a segmentation fault.
// As this was fixed in #11262, this test checks that no segfault
// occurs when passing the invalid file `bar` to -Z ls.
// See https://github.com/rust-lang/rust/issues/11259
