error: future cannot be sent between threads safely

LL | spawn(async {

= help: within `[async block@$DIR/issue-67252-unnamed-future.rs:18:11: 21:6]`, the trait `Send` is not implemented for `*mut ()`
note: future is not `Send` as this value is used across an await
--> $DIR/issue-67252-unnamed-future.rs:20:16

LL | let _a = std::ptr::null_mut::<()>(); // `*mut ()` is not `Send`
| -- has type `*mut ()` which is not `Send`
LL | AFuture.await;
| ^^^^^^ await occurs here, with `_a` maybe used later
LL | });
| - `_a` is later dropped here
note: required by a bound in `spawn`
