+// 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.
