ICE in 1.60.0-beta.1: `thread 'rustc' panicked at 'Box<dyn Any>', compiler/rustc_errors/src/lib.rs:1160:9`

Code

https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=8246316eaa144bdcfc3f421aa56fd785

use std::collections::VecDeque;

pub struct BuildPlanBuilder {
    acc: VecDeque<(String, String)>,
    current_provides: String,
    current_requires: String,
}

impl BuildPlanBuilder {
    pub fn or(&mut self) -> &mut Self {
        self.acc
            .push_back(self.current_provides, self.current_requires);
        // ...
        self
    }
}

Note: In the example above, there are parens missing around the tuple being passed to .push_back(), which once added in, resolves the ICE.

Sorry, that i didn't claim this before,
I found a fix for this, should I create a pr for it, or do you wanna fix this?
