I've managed to repro with this on 1.66.0-nightly (2022-10-25 bed4ad65bf7a1cef39e3)

use tokio::task;

struct StructA {
    b: StructB,
}

impl StructA {
    async fn foo(&self) {
        let bar = self.b.bar().await;
        task::spawn_blocking(move || {
            self.b;
        });
    }
}

struct StructB {}

impl StructB {
    async fn bar(&self) -> Option<u8> {
        None
    }
}

Error output:

Hi @TaKO8Ki thanks for looking into this issue. I saw you added the "E-needs-mcve" label. Wondering how to improve this example?

compiler-errors · 2022-10-27T15:55:22Z

@agostbiro that's a sufficient example, I can look into it.

…gillot Don't carry MIR location in `ConstraintCategory::CallArgument` It turns out that `ConstraintCategory::CallArgument` cannot just carry a MIR location in it, since we may bubble them up to totally different MIR bodies. So instead, revert the commit a6b5f95, and instead just erase regions from the original `Option<Ty<'tcx>>` that it carried, so that it doesn't ICE with the changes in rust-lang#103220. Best reviewed in parts -- the first is just a revert, and the second is where the meaningful changes happen. Fixes rust-lang#103624
