Everything in C is undefined behavior: any operation on uninitialized or misused data can lead to surprise results, crashes, or security flaws. Rely on well-defined rules, not luck. #C #Programming #UndefinedBehavior https://t.co/p9hJzwOhrM
Did you know that C undefined behavior is virtually omnipresent in non-trivial programs? Even 30-year experts admit that writing a safe C program is nearly impossible 😱. Let's discuss! #Coding #CProgramming #UndefinedBehavior

We can't say for sure, but it's quite likely. This is another textbook case of #UndefinedBehavior in C++ code. Dereferencing `std::map::end()` causes this, as this iterator points past the last element in a `std::map`.
We know, #undefinedbehavior is out of compilers' scope. However, it doesn't mean that their codebase is immune to it. Here we can see a classic undefined behavior scenario, triggered only if 'regIdx == 31'. Probably, it seems impossible or very unlikely, so the error has been unnoticed. But who knows what tomorrow will bring?
A critical undefined behavior vulnerability (GHSA-5w5r-mf82-595p) affects Cap'n Proto. Update to 0.24.0 to ensure stability and data integrity. #Capnp #SecurityAdvisory #UndefinedBehavior https://t.co/VlOSRuCCko

Why is it the chapter 12 of 11? We couldn't resist highlighting the favorite error of C and C++ programmers that even has its own name—the Off-by-one Error. We also didn't want to break the tradition ;)

C++ programmer's guide to undefined behavior: part 11 of 11
#cpp #undefinedbehavior
17/19 Undefined behavior in programming can both enable and disable optimizations, challenging the common belief that it only allows for more aggressive optimization. #UndefinedBehavior ⬇️

Your attention is invited to the ninth part of an e-book on #undefinedbehavior. It's a kind of C++ programmer's guide to UB and to its most secret and exotic corners.

Your attention is invited to the seventh part of an e-book on undefined behavior. This is not a textbook, as it's intended for those who are already familiar with #cpp #programming. It's a kind of C++ programmer's guide to #undefinedbehavior.
Your attention is invited to the sixth part of an e-book on undefined behavior. Enjoy! 😉
