Checklist

• I have already looked over the issue tracker for similar issues.
• This issue can be reproduced on Rust's stable channel.

diesel is broken on nightlies 05-15->(likely) 05-23 due to a regression in rustc. rustup run nightly-2018-05-14 cargo install diesel_cli. Or compile with stable. See #1700. The errors changes in 1.3, but the cause appears to be the same.

[weiznich]

Basically a duplicate of #1700 .
Will be hopefully fixed with the next rustc nightly.
