These risks are mostly, and often entirely, gone when you write modern C++. You don't lose track of them, because you don't track them, and you only use them when you don't need to track them. (Except for inside the implementations of a few data structures, which one can think of as the equivalent of unsafe code in Rust). Of course I'm generalizing here, but again, you just don't write C-style code, and you don't have those problems.

(You may have some other problems of course, C++ has many warts.)
