// The `crate_name` rustc flag should have higher priority
// over `#![crate_name = "foo"]` defined inside the source code.
// This test has a conflict between crate_names defined in the .rs files
// and the compiler flags, and checks that the flag is favoured each time.
// See https://github.com/rust-lang/rust/pull/15518
