Rollup merge of #30115 - nilcons-contrib:fix-book-stack, r=steveklabnik
The `f` argument will reference the actual value in the `d` box, not the box in the `bar`'s stack frame.
I am just learning Rust, so I don't know how to explain this well, but just from `f`'s type it is clear that it will be a pointer to an `i32`, not a pointer to a pointer. Some `println!("{:p}", ...)`'s can easily confirm this.
I would actually suggest to remove/simplify this part of the example. This is a subtle issue that can easily confuse people at the early stages of familiarizing with the language. (As I got confused by it. :))
