note: Run with `RUST_BACKTRACE=1` for a backtrace.
query stack during panic:
#0 [borrowck] processing `main`
  --> no-std.rs:10:1
   |
10 | fn main() {}
   | ^^^^^^^^^
end of query stack

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
