To people who are reading:

This Github issue contains 2 ICE issues

The original code I minimised causes an ICE on stable, beta and nightly
But the further-minimised code only causes ICEs on beta and nightly, and therefore is a separate issue

    Minimised example:

    pub trait MyComponent {
    type Properties;
}

impl<M> MyComponent for M
where
    M: 'static,
{
    type Properties = ();
}

fn main() {
    |_: <&u8 as MyComponent>::Properties| {};
}

    image
    The minimised code is actually a separate issue; no ICE under stable.

    This is probably it even though this panics at compiler/rustc_borrowck/src/region_infer/mod.rs:2174:9, which has a different line number to the original ICE.
