Clippy crashes on packed_struct repository

[samueltardieu]

Clippy 0.0.180 crashes on one of my students program which uses the packed_struct crate. And indeed, the packed_struct crate tests fail as well:

% git clone https://github.com/hashmismatch/packed_struct.rs
% cd packed_struct.rs/packed_struct_tests
% cargo clippy
[…]

Running cargo build or cargo test in this directory terminates succesfully.

This appears to be a problem with workspace handling. cargo clippy --all works, btw.

The error appears to stem from https://github.com/rust-lang-nursery/rust-clippy/blob/master/src/main.rs#L124

Looks like this is fixed with 0.0.191 (possibly in #2585). I can't reproduce this anymore, so I'm going ahead and close this.

@samueltardieu Feel free to re-open if you still get this crash with 0.0.191.
