auto-reduced (treereduce-rust):

type Field3 = i64;

#[repr(C)]
union DummyUnion {
    field3: Field3,
}

const UNION: DummyUnion = loop {};

const fn read_field2() -> Field2 {
    const FIELD2: Field2 = loop {
        UNION.field3
    };
}

original:

type Field3 = i64;

#[repr(C)]
union DummyUnion {
    field3: Field3,
}


const UNION: DummyUnion = loop {};



const fn read_field2() -> Field2 {
    const FIELD2: Field2 = loop {UNION.field3};
}
