// This test makes sure that gdb does not set unwanted breakpoints in inlined functions. If a
// breakpoint existed in unwrap(), then calling `next` would (when stopped at `let s = ...`) stop
// in unwrap() instead of stepping over the function invocation. By making sure that `s` is
// contained in the output, after calling `next` just once, we can be sure that we did not stop in
// unwrap(). (The testing framework doesn't allow for checking that some text is *not* contained in
// the output, which is why we have to make the test in this kind of roundabout way)
fn bar() -> int {
    let s = Some(5).unwrap(); // #break
