NR2: ICE: in resolve_path_to_trait, at rust/typecheck/rust-hir-trait-resolve.cc:160 `impl X for Y { type X = .. }`

auto-reduced (treereduce-rust):

//@compile-flags: -frust-incomplete-and-experimental-compiler-do-not-use -frust-name-resolution-2.0
pub struct GenericType;

impl Output for GenericType<{ 42 }> {
    type Output = ();
}

original:

#![cfg_attr(full, allow(incomplete_features))]
#![cfg_attr(full, allow(incomplete_features))]
#![cfg_attr(min, feature(min_const_generics))]

// All of these three items must be in `lib2` to reproduce the error

pub trait TypeFn {
    type Output;
}

pub struct GenericType<const B: i8>;

// Removing the braces around `42` resolves the crash
impl Output for GenericType<{ 42 }> {
    type Output = ();
}

Please submit a full bug report, with preprocessed source (by using -freport-bug).
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

Start by compiling the reduced Rust reproducer with the command provided and inspect resolve_path_to_trait in gcc/rust/typecheck/rust-hir-trait-resolve.cc around line 160, following the call path shown in the backtrace. Done means the reproducer no longer triggers an internal compiler error in the name-resolution 2.0 mode.
