I'm trying to work through the code coverage example at GitHub - marco-c/rust-code-coverage-sample: Example of code coverage instrumentation in Rust. Everything "runs" fine, but when I examine the coverage report, it says 0% coverage.
I'm running an Intel Mac on OS 10.15.6, Rust 1.54.0 nightly (cargo 070e459c2 2021-05-11).
Is this a known issue?
Any suggested workarounds? Same happens in my own real project and is making dev work more difficult.
