Running RUSTDOCFLAGS=--document-private-items ./x doc --stage 1 library fails with this error:
Documenting alloc v0.0.0 (/home/lukas/code/rust/library/alloc)
error[E0080]: evaluation of constant value failed
--> library/alloc/src/collections/btree/node.rs:1679:38

1679 | const TRAVERSAL_PERMIT: () = panic!();
| ^^^^^^^^ the evaluated program panicked at 'explicit panic', library/alloc/src/collections/btree/node.rs:1679:38

= note: this error originates in the macro `$crate::panic::panic_2021` which comes from the expansion of the macro `panic` (in Nightly builds, run with -Z macro-backtrace for more info)

Without --stage 1 it emits the same error, but "passes". Found in #105848, specifically 3223b6c.
Also, not really related, but ./x doc --open library doesn't open anything.
