tests/run-make/debug-assertions/rmake.rs

// debug.rs contains some "debug assertion" statements which
// should only be enabled in either non-optimized builds or when
// `-C debug-assertions` is set to yes. These debug assertions
// are guaranteed to fail, so this test checks that the run command
// fails where debug assertions should be activated, and succeeds where
// debug assertions should be disabled.
// See https://github.com/rust-lang/rust/pull/22980
