@Alexendoo, actually this still repros for rust#93646 if the lifetime is provided:

struct X<const N: usize = {
    let s: &'static str; s.len()
}>;

pub fn main() {}

That'll be fixed in rust#93691, but should we edit this test to better record this distinction?

[Alexendoo]

Ahh I didn't think to try that, I realise also I didn't need the s + 1. It could be worth adding one of the form

struct X<const N: usize = {
    let n: usize; n
}>;

pub fn main() {}

To be clear it's solely about uninitialised variables, but it's fairly minor and I see the PR is already queued for merge

[compiler-errors]

Yeah no worries in that case.
