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 1.58.0-nightly (29b124802 2021-10-25) running on x86_64-apple-darwin

note: compiler flags: -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C incremental --crate-type lib

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

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

The problem here is that T::VAL + 1 is not resolvable, hence we can't prove that [i32; T::VAL + 1]: SmallArray. #90023 would fix the ICE and output the following error:

error[E0277]: the trait bound `[i32; _]: SmallArray` is not satisfied
  --> ../unknown-vars-resolve-instance/test.rs:22:13
   |
22 |     consume(make_array::<T>());
   |     ------- ^^^^^^^^^^^^^^^^^ the trait `SmallArray` is not implemented for `[i32; _]`
   |     |
   |     required by a bound introduced by this call
   |
note: required by a bound in `consume`
  --> ../unknown-vars-resolve-instance/test.rs:15:15
   |
15 | fn consume<T: SmallArray>(t: T) {}
   |               ^^^^^^^^^^ required by this bound in `consume`
help: consider extending the `where` bound, but there might be an alternative better way to express this requirement
