…=nikomatsakis Add test for old compiler ICE when using `Borrow` The original issue was caused by implementing `Borrow` on a local type and using the tokio-reactor crate which had this impl: https://github.com/tokio-rs/tokio/blob/tokio-0.1.4/tokio-reactor/src/poll_evented.rs#L547-L577 This causes an ICE on Rust 1.27.0: ```console $ RUSTUP_TOOLCHAIN=1.27.0 rustc src/test/ui/issues/issue-50687-ice-on-borrow.rs error: internal compiler error: librustc/traits/structural_impls.rs:180: impossible case reached thread 'main' panicked at 'Box<Any>', librustc_errors/lib.rs:554:9 note: Run with `RUST_BACKTRACE=1` for a backtrace. error: aborting due to previous error note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports note: rustc 1.27.0 (3eda71b 2018-06-19) running on x86_64-apple-darwin ``` Closes rust-lang#50687
