error[E0594]: cannot assign to `*ptr`, which is behind a `*const` pointer
--> $DIR/no-invalid-mut-suggestion-for-raw-pointer-issue-127562.rs:7:14

LL | unsafe { *ptr = 3; }
| ^^^^^^^^ `ptr` is a `*const` pointer, so the data it refers to cannot be written
|
help: consider changing this to be a mutable pointer

LL | let ptr = &mut raw const val;
