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