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

   4 LL | static foo: &Y::X = &*Y::foo(Y::x as *const Y::X);
   5    |                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ dereference of raw pointer
   6    |
   7    = note: raw pointers may be null, dangling or unaligned; they can violate aliasing rules and cause data races: all of these are undefined behavior

   9 error[E0133]: use of extern static is unsafe and requires unsafe function or block

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