The warning can be reproduced with 1.63 but not with 1.64.
$ rustc +1.63 tests/ui/lint/unused/const-local-var.rs
warning: constant `F` is never used
--> tests/ui/lint/unused/const-local-var.rs:14:9

14 | const F: i32 = 2;
| ^^^^^^^^^^^^^^^^^

= note: `#[warn(dead_code)]` on by default
$ rustc +1.64 tests/ui/lint/unused/const-local-var.rs
Add a regression test to prevent the problem from re-appearing.
Closes #69016
