error: internal compiler error: unexpected panic

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 1.45.0-nightly (fa51f810e 2020-04-29) running on x86_64-unknown-linux-gnu

note: compiler flags: -C opt-level=3 -C bitcode-in-rlib=no -C codegen-units=16 -C debuginfo=2 -C incremental -C link-arg=-fuse-ld=lld --crate-type lib

note: some of the compiler flags provided by cargo are hidden
