Another one:

struct Sched {

impl Sched {

    let s = Sched { i: 4 };

The issue here seems to be that mir_build steals THIR of closures before they are checked by their parent function.

Ensure that THIR unsafety check is done before stealing it

This ensures that THIR unsafety check is done before stealing it by running it on the typeck root instead of on a closure, which does nothing.
