Kettled twice. Extra chewy, extra trustworthy.
Summary
The article discusses writing bounds-safe code in C with arrays, highlighting the issue of array bounds violation and how compilers can detect such problems at translation time. It also addresses the challenge with arrays of run-time length and the use of -fsanitize=bounds to detect errors at run time.
