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/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.61.0-nightly (458262b13 2022-03-09) running on x86_64-unknown-linux-gnu

Backtrace

error[E0152]: found duplicate lang item `sized`
 --> :4:1
  |
4 | trait A {}
  | ^^^^^^^^^^

  = note: the lang item is first defined in crate `core` (which `std` depends on)
  = note: first definition in `core` loaded from /opt/compiler-explorer/rust-nightly/lib/rustlib/x86_64-unknown-linux-gnu/lib/libcore-0e3656b1fda5fd7b.rlib
  = note: second definition in the local crate (`example`)
error[E0277]: the size for values of type {integer} cannot be known at compilation time

--> :7:13

7  |     let _ = 0..80*25;

|             ^^^^^^^^ doesn't have a size known at compile-time

= help: the trait Sized is not implemented for {integer}

note: required by a bound in std::ops::Range
