I also am running into this bug with a very similar-looking backtrace. Managed to create a minimal example: #![feature(generic_const_exprs)]
pub trait Const {
const N: usize;
}
pub trait Arr<T>: Const {
type Arr;
}
impl<T, C: Const> Arr<T> for C
where
[T; C::N]:,
{
type Arr = [T; C::N];

this may be somewhat OT, but
I can absolutely understand why rustdoc needs to have its own FLAGS for compilation, and I can see how it would be useful into the future especially, but it would be nice if rustdoc accepted debugging flags like this one from RUSTFLAGS. Or maybe |

You don't necessarily want the rust flags for rustdoc while playing with both though. |

Hmm. No, I actually can't think of a situation where I would want -Ztreat-err-as-bug to not apply to rustdoc. |
Hmm, I don't know if this is quiiite the same, @clarfonthey, because @calebzulawski was actually trying to remove |

That's fair; I'd be interested to see if you manage to narrow down a minimal case what yours would be. That said, I think @oli-obk's analysis is probably right. |

i'm also experiencing this (with in the workspace, the crate that defines the trait documents without any errors. i can try to get a minimal example working, but for now, the specific workspace where this occurs is this. the trait is defined in the crate $ rustc +nightly --version --verbose

It's... kinda hard to thin this down, because it only breaks when I run
cargo docin the workspace of this commit:rust-lang/portable-simd@744169a
It may be due to PG-PSIMD's own sins against a sensible compilation flow, but also it may not be! I am not sure.
