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 1.32.0-nightly (1f57e4841 2018-11-23) running on x86_64-apple-darwin
note: compiler flags: -C opt-level=3 -C target-cpu=native -C lto=thin --crate-type lib
note: some of the compiler flags provided by cargo are hidden
