5 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `UnsafeCell<i32>` may contain interior mutability and a reference may not be safely transferrable across a catch_unwind boundary
7 = help: the trait `RefUnwindSafe` is not implemented for `UnsafeCell<i32>`
8 = note: required because of the requirements on the impl of `UnwindSafe` for `*const UnsafeCell<i32>`
9 note: required by a bound in `assert`
