Well, it would be a reproducer of the ICE if I replaced the body with 0
Suggested change
| T::generate() | |
| 0 |
but then the test would become a bit boring since we wouldn't actually use anything from ~const Aux. With T::generate() nightly rustc incorrectly fails with mismatched types // expected `host`, found `true` since the ICE is a delayed bug. Ofc I could add revisions to this test or another file.

It's not that big of a deal. Showing that it doesn't ICE (we can lower the where clause) and that it works correctly seems like a fine test.
