If you want to use the 0.10 release on nightly, you will need to clone the repo, git reset --hard v0.10.0, and git cherry-pick this and this commit.

On Ubuntu 18.04, this is still affecting building with official crate (0.10.0) and rust 1.34.0. Building is successful when using the code in master with rustc 1.36.0:
