// ISSUE(77553): Originally, this test had `Err(1)` on line 22 (instead of `Ok(())`) and
// `std::process::exit(2)` on line 26 (instead of `Err(1)`); and this worked as expected on Linux
// and MacOS. But on Windows (MSVC, at least), the call to `std::process::exit()` exits the program
// without saving the InstrProf coverage counters. The use of `std::process:exit()` is not critical
// to the coverage test for early returns, but this is a limitation that should be fixed.
