Description
While working on an experimental runtime rio and using a couple of experimental features I found that the compiler while in resolving the async call on a trait crash badly.
This is a minimal reproducible example
#![feature(async_fn_in_trait)]
#![feature(associated_type_defaults)]
use rio_rt::runitime as rio;
trait AsyncTrait {
async fn foo(&self) -> Result<(), ()>;
}
struct AsyncStruct;
impl AsyncTrait for AsyncStruct {
async fn foo(&self) -> Result<(), ()> {
Ok(())
}
}
async fn run_async_workflow(a: &impl AsyncTrait) -> Result<(), ()> {
a.foo().await
}
fn main() {
rio::block_on(async {
let obj = AsyncStruct{};
run_async_workflow(&obj).await.unwrap();
});
rio::wait();
}and this is the stacktrace generated

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 1.66.0-nightly (a6b7274a4 2022-10-10) running on x86_64-unknown-linux-gnu
note: compiler flags: --crate-type bin -C embed-bitcode=no -C debuginfo=2 -C incremental=[REDACTED]
note: some of the compiler flags provided by cargo are hidden

error: could not compile `rio_triage_await`; 1 warning emitted
N.B: I guess this happens with any runtime? BTW also if happens only with rio the compiler should not crash, but I do not think this is related to a specific runtime, but I guess instead, the runtime triggers the resolution of the futures
