With the current beta, cargo +beta clippy is giving an ICE for the Rug crate, while cargo +stable clippy works fine, and cargo +beta check works fine too.

$ cargo +stable clippy --version
clippy 0.0.212 (3aea860 2019-09-03)

$ cargo +beta clippy --version
clippy 0.0.212 (157edad 2019-09-22)

$ #Rug version 1.6.0

$ RUST_BACKTRACE=1 cargo +beta clippy
# ...

I've just tested on nightly and it's fixed there, I'm guessing by #4590.

Will the beta be updated with that fix before 1.39.0 is released, or will clippy ICE for the duration of the 1.39.0 release?

I think the fix could be backported given how widespread is this issue.

Yeah, I think we should backport it to beta. I'm on it.

[Beta] Backport Clippy ICE fix to beta

There was an ICE in Clippy, when compiling `mysql_common`. Since this is a pretty popular crate, and there were a bunch of Clippy issues in the last few days, I think it is worth it to backport the fix (rust-lang/rust-clippy#4590) to beta.
