error: future cannot be sent between threads safely
  --> $DIR/issue-65436-raw-ptr-not-send.rs:12:5

LL |     assert_send(async {
   |     ^^^^^^^^^^^ future created by async block is not `Send`
   |
   = help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `*const u8`
note: future is not `Send` as this value is used across an await

   |                 ----------------  ^^^^^^ await occurs here, with `std::ptr::null()` maybe used later
   |                 |
   |                 has type `*const u8` which is not `Send`
note: `std::ptr::null()` is later dropped here

help: consider moving this into a `let` binding to create a shorter lived borrow
