ice: `Should not be resolving bound region.`

[matthiaskrgr]

code was reduced from a diagnostic issue: #97680
Unfortunately I can't bisect this since we don't have nightly debug assertion builds

use std::future::Future;

fn hrc<R, F: for<'a> AsyncClosure<'a, (), R>>(f: F) -> F {
    f
}

fn main() {
    hrc(|x| async {});
}

trait AsyncClosure<'a, I, R>
where
    I: 'a,
{
}

impl<'a, I, R, Fut, F> AsyncClosure<'a, I, R> for F
where
    I: 'a,
    F: Fn(&'a I) -> Fut,
    Fut: Future<Output = R> + Send + 'a,
{
}

error: 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 1.75.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -Z dump-mir-dir=dir

query stack during panic:
#0 [typeck] type-checking `main`
#1 [analysis] running analysis passes on this crate
end of query stack

[lqd]

note: compiler flags: -Z dump-mir-dir=dir

What's this in the backtrace, is that flag important to reproduce the ICE?

[matthiaskrgr]

When I check for ICEs I check several batches of flags at a time to not have to run rustc 40 times per file and this is one of them (also some files only compile before/after a certain edition)
When I later generate the report, there maybe still be some of these "original flags" left which are actually not needed to repro the ice (bug on my end, may fix it one day), but I already filter them out from the "flags needed to repro" for the report.

I checked manually and you only need --edition=2021 with a rustc that has debug assertions enabled to repro. :)
