s study of uses of C#’s unsafe on StackOverflow and prevalence of vulnerabilities, and that all programs eventually call trusted native libraries or operating system code. That’s pretty easy to statically guarantee, except for some cases of the unused parts of lazily constructed array/vector storage.
