error: future cannot be sent between threads safely
--> $DIR/issue-67252-unnamed-future.rs:21:5

LL | spawn(async {
| ^^^^^ future created by async block is not `Send`

= help: within `[async block@$DIR/issue-67252-unnamed-future.rs:21:11: 25:6]`, the trait `Send` is not implemented for `*mut ()`
= note: consider using `std::sync::Arc<*mut ()>`; for more information visit <https://doc.rust-lang.org/book/ch16-03-shared-state.html>
note: future is not `Send` as this value is used across an await

LL | let a = std::ptr::null_mut::<()>(); // `*mut ()` is not `Send`

LL | AFuture.await;
| ^^^^^ await occurs here, with `a` maybe used later
note: required by a bound in `spawn`

LL | fn spawn<T: Send>(_: T) {}
