(somewhat) minimal repro: https://github.com/asg0451/rust-coz-breaker

Anecdotally, coz worked fine in my actual program, until I added rayon & channels & parallelism.

Ubuntu 20.04, coz from apt (I don't see a --version flag)

Would you take a PR to change build to CMake?

As a first step to building on windows it would be good to change the build to CMake. Would you take that PR?
