See, I'm coming from the perspective that people who work with Language X have learned where all the dark corners of Language X are. Would you expect anything else? C does not have more dark corners than Python, Ruby, PHP, LISP, Rust, etc. Part of being an expert is knowing the language you're working with, and knowing the limits of your tools. When you update GCC and they add some bonkers optimization strategy that introduces new undefined behavior, you should know about that. Even experienced "Rust kernel wizards" will make mistakes. You'll see.
