Compiler crash with type_alias_impl_trait on the very latest version #100818

BattyBoopers · 2022-08-20T21:05:04Z

Code

#![feature(type_alias_impl_trait)]
use std::future::Future;

fn main() {
    type SomeFuture<'t> = impl 't + Future<Output = ()>;
    type SomeClosure = impl for<'t> FnOnce(&'t str) -> SomeFuture<'t>;
    fn coerce_closure(f: SomeClosure) {}
    coerce_closure(|x: &str| async move {});
}

This crashes with the very latest version (cargo +nightly-2022-08-19 run), but not with the previous version (cargo +nightly-2022-08-18 run)

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.65.0-nightly (e1b28cd2f 2022-08-19) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type bin -C embed-bitcode=no -C debuginfo=2 -C incremental

note: some of the compiler flags provided by cargo are hidden

query stack during panic:
#0 [mir_borrowck] borrow-checking `main`
#1 [type_of] computing type of `main::SomeFuture::{opaque#0}`
#2 [check_mod_item_types] checking item types in top-level module
#3 [analysis] running analysis passes on this crate
end of query stack
