The coverage failure is because with rust 1.72.0, cargo kcov broke. It relies on parsing rustc's stdout for discovering where test executable are located, and the format for that changed (cargo-kcov expects the log message to start with "Running rustc (...)", but since 1.72.0 cargo prints out the fully qualified path to rustc, resulting in cargo-kcov not finding any binaries). Since cargo-kcov is unmaintained since 2019, I'll go ahead and replace it with grcov.
