High recursion_limit plus recursive trait resolution error results in SIGSEGV

[konnorandrews]

I was playing around with the code I had from https://github.com/rust-lang/rust/issues/112991 and I increased the recursion limit past reasonable, and it resulted in a SIGSEGV. I am not sure if this is a result of a known issue or not.

Code

#![recursion_limit = "2000"] // The value here doesn't really matter as long as its big.

fn main() {
    let _x: () = of(); // doesn't work

    let _x: () = of::<()>(); // works
}

trait MyTrait {}

impl<'a> MyTrait for &'a () {}

mod other {
    use super::MyTrait;

    fn some_function() {
        struct hello_from_inside_other_mod<T>(T);

        impl<T> MyTrait for &'_ (T,) where for<'a> &'a T: MyTrait {}
    }
}

fn of<'a, T: 'a>() -> T
where
    &'a T: MyTrait,
{
    todo!()
}
