error[E0133]: borrow of layout constrained field with interior mutability is unsafe and requires unsafe function or block
--> $DIR/ranged_ints3_match.rs:14:17

LL | NonZero(ref x) => { x }
| ^^^^^ borrow of layout constrained field with interior mutability

= note: references to fields of layout constrained fields lose the constraints. Coupled with interior mutability, the field can be changed to invalid values

= note: mutating layout constrained fields cannot statically be checked for valid values
