   39|       |// `std::process::exit(2)` on line 26 (instead of `Err(1)`); and this worked as expected on Linux
   40|       |// and MacOS. But on Windows (MSVC, at least), the call to `std::process::exit()` exits the program
   41|       |// without saving the InstrProf coverage counters. The use of `std::process:exit()` is not critical
   42|       |// to the coverage test for early returns, but this is a limitation that should be fixed.
   43|       |//
   44|       |// FIXME(richkadel): Consider creating a new tests for coverage when calling `std::process::exit()`,
   45|       |// move the `ISSUE` comment to that test, and implement a new test directive that supports skipping
   46|       |// coverage tests when targeting specific platforms (at least skipping Windows, or MSVC if the
   47|       |// problem exists on MSVC only).
