// Notes:
//   1. Compare this program and its coverage results to those of the similar tests `abort.rs` and
//      `try_error_result.rs`.
//   2. Since the `panic_unwind.rs` test is allowed to unwind, it is also allowed to execute the
//      normal program exit cleanup, including writing out the current values of the coverage
//      counters.
