Unused lifetime cause ICE

[DutchGhost]

The following code ICE's on stable, beta and nightly:

use core::mem::size_of;

struct Bug<'s> {
    array: [(); size_of::<&Self>()],
}

Feel free to close if this is a duplicate of #56445.
What I noticed is that when the lifetime is removed, it just compiles fine:

use core::mem::size_of;

struct Bug {
    array: [(); size_of::<&Self>()],
}

Triage:
This is no longer ICE with the latest nightly as well as #56445: https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=a9cdb892a6353014ff5b57258e3cd22c
