I ran into what I believe is the same issue. For what it's worth, I found this much shorter example:

#![allow(incomplete_features)]
#![feature(const_generics, const_evaluatable_checked)]

struct Foo<'a> {
    _r: &'a u8,
}

trait FooTrait {
    const FOO_LEN: usize;

    fn foo_fun(&self, expr: [u8; Self::FOO_LEN]);
}

impl<'a> FooTrait for Foo<'a> {
    const FOO_LEN: usize = 1;

    fn foo_fun(&self, _expr: [u8; 1]) {
        unimplemented!()
    }
}

Unfortunately, the code I provided a few months ago is not the same error. I know that because my code now compiles on nightly, but the code in the original issue does not.
