error[E0133]: dereference of raw pointer is unsafe and requires unsafe function or block
|

--> $DIR/issue-16538.rs:14:22
|

LL | static foo: &Y::X = &*Y::foo(Y::x as *const Y::X);
|
||
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ dereference of raw pointer
|
||
|
|
|
|
||
|
|
= note: raw pointers may be null, dangling or unaligned; they can violate aliasing rules and cause data races: all of these are undefined behavior

= note: extern statics are not controlled by the Rust type system: invalid data, aliasing violations or data races will cause undefined behavior
