Safety of casting from `*mut T` to `*mut ()` to `*mut T` (+dynamic linking?)

Though @kornel says that Rust doesn't use TBAA. I can see why Rust would be compiled this way, but if it's not too much trouble, is it possible you could provide a source?

I don't know of an official page that calls out the lack of such UB explicitly, but you can infer it from various other documentation, or just search GitHub for many comments pointing this out to others or taking it for granted.^[1]
