error[E0713]: borrow may still be in use when destructor runs
--> $DIR/issue-45696-scribble-on-boxed-borrow.rs:34:5

LL | fn scribbled<'a>(s: Scribble<'a>) -> &'a mut u32 {
| -- lifetime `'a` defined here
LL | &mut *s.0
| ^^^^^^^^^ returning this value requires that `*s.0` is borrowed for `'a`
LL | }
| - here, drop of `s` needs exclusive access to `*s.0`, because the type `Scribble<'_>` implements the `Drop` trait
