If you use the GC (and don't go out of your way to hide pointers/references from it) it's as memory-safe as any GC'ed language. If you avoid the GC and do your memory management manually you at least have RAII so it shouldn't be any less safe than C++. D also includes some (experimental?) language features which aim to improve memory safety[1] but they're nowhere near as robust as Rust's type system.
