On 13e5eda I am seeing the following tests fail:

$ cargo test --test source
    Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs

It looks like travis is seeing the same thing here: https://travis-ci.org/steveklabnik/rustdoc/jobs/261029045

This is passing for me locally :/

[mgattozzi]

Same. @steveklabnik I wonder if we have something on our machines that's letting it pass but others might not.

[steveklabnik]

The plot thickens: I ran rustup update and now it fails.

[steveklabnik]

Random shot in the dark, rust-lang/rust#43611 was merged. hrm

[euclio]

Maybe we need to update the rls-analysis crate? I think an upgrade is blocked by rust-dev-tools/rls-analysis#81, though.

@euclio it's like you read my mind
