ICE: thread 'rustc' panicked at 'Box<Any>'

[peterjoel]

This occurred when running cargo clippy on a workspace with around 40 child crates. I have not included the full log, for corporate security reasons, but I can probably provide more specific information on request.

[jonas-schievink]

Thanks for the report! Please provide a backtrace by running with RUST_BACKTRACE=1.

Does this also happen when running cargo check or cargo build?

[peterjoel]

With backtrace, it doesn't give much more info:

[mati865]

That's odd, can you try on Linux?

[peterjoel]

cargo build and cargo test work without errors.

[peterjoel]

In Linux:

[mati865]

It's unknown Clippy bug, @jonas-schievink can you move this issue to Clippy repo?

[peterjoel]

FYI I also checked with 1.37.0 toolchain and the issue does not occur.

[tesuji]

Could you try latest nightly that has clippy?
Edit: Could you try nightly-2019-10-04?

[peterjoel]

Latest nightly does not support clippy.
Edit: Just saw your edit. I will try that version.

[jonas-schievink]

Unfortunately I can't move the issue since I don't have push access to https://github.com/rust-lang/rust-clippy, but yeah, a bug in Clippy, so it should be filed there.
