"Behold, the epic quest for 'Dependable C' - because nothing screams #reliability like undefined behavior and broken VLAs 🤦♂️! In a dazzling display of verbosity, they ironically try to fix C with more convoluted #C23 and mythical #C2Y, because adding chaos is the path to safety, right? 🤔🔧"

🚀😂 Oh, look! Another grandiose plan to sprinkle some #Rust magic on #C, only to be abandoned faster than you can say "undefined behavior". But hey, at least the proposal taught us that gluing #safety onto C is like trying to attach wings to a car and expecting it to fly 🚗✈️.

I stumbled over a C compiler doing unexpected things when finding programs using undefined behaviour. Sadly I don't remember more. Has anyone a pointer for me?
@wyatt I've seen others interpret it as rav1d offering a $20,000 bug bounty for dav1d, the C decoder. If you find exploitable undefined behavior that the dav1d devs have to spend 5% of CPU time to prevent, you win.

“[…] But they also made some mistakes… which is not too surprising when you are doing this kind of work. And I would like rust ideally not to repeat these mistakes. I think we can make our own new and fun unique mistakes”

Ah yes, because what could be more exhilarating than "fun" with undefined behavior and C libraries? 🤔 Just when you thought C couldn't get any more "entertaining," here comes a blog post to remind you that the real circus is in the code you *didn't* know was breaking things. 🎪🔧

I put an overview of my preliminary (!) analysis of undefined behavior in the core language and the status in C2Y into the ISO WG14 document log.

Ah, yes, let's all gather 'round the campfire to hear the age-old tale of #C and #C++, where speed demons rule and correctness is just a bedtime story 🙄🚀. Apparently, back in 1989, the wizards of #programming thought "undefined behavior" sounded like a great idea—because who doesn't love a little #chaos in their code? 😜🤯 #YOLOCoding #UndefinedIsTheNewDefined

Today's adventures in C++ culminate in a failure to initialize variables leading to a bool having a value of 193 (?!), which somehow lead to a return statement going down an utterly insane path that resulted in an illegal instruction crash.

New on the blog: A brief detour, as some of the support code I wrote for last week's Amiga project went *terribly* wrong. A tale of berzerk optimizing compilers and undefined behavior, and a reconstruction of its antics.
