I'm trying to build my crate at this commit: https://github.com/fizyk20/atm-refraction/tree/a7f38e582d507345f0f6bddbf769244caee0fe70
cargo build --releaseran on Rust 1.34.1 doesn't finish for at least a few minutes (I admit I haven't been too patient with letting it run for a long time, as I knew it used to compile quite quickly, but I can safely say that it wasn't able to finish for me in at least 5 minutes). A debug build (cargo build) finishes in about 15 seconds.I checked on another Rust version to make sure that it's different, and indeed, compilation of the same commit on 1.31.0 in release mode takes 24 seconds. Nightly 1.36.0 2019-05-03 can't finish just like 1.34.1.
I haven't tried versions other than 1.31.0, 1.34.1 and 1.36.0 nightly so far, but I can do so if needed.
I'm on Gentoo Linux on x86_64. All tested Rust versions installed via
rustup.If any other information is required, please let me know.
