Description
I have a problem with tests execution. Every time, when I do cargo check, subsequent launch of cargo test fails.
It reproduces like this:
cargo clean
cargo test # SUCCEED
cargo test # SUCCEED
cargo check
cargo test # FAILED
It worked in such a way for me with different releases.
My current environment:
$ rustup show
Default host: x86_64-unknown-linux-gnu
nightly-x86_64-unknown-linux-gnu (default)
rustc 1.22.0-nightly (02a24dbdd 2017-10-13)
Failed test:

I don't understand why it happend. Does it reproduce for anybody else?
