I define undefined behaviour as a bug in C++. Now C++ is memory-safe!
btw, it's not actually that hard to write correct code in C++, easier than in C because you have all the container types. The problem is that nothing will tell you when you write incorrect code - there's no guarantee.
UB is part of the C++ standard. Surely you can understand the difference between the C++ standard and bugs in compilers implementing the C++ standard. This is that.
Which part of the Rust standard does cve-rs violate?

I mean, sure, insofar as such a thing would also imply that a) the standard would need quite a bit of cleanup/clarification work to not contradict your definition, and b) the main optimizing C++ compilers are miscompiling code, analogous to how cve-rs is a rustc miscompilation rather than an issue with Rust itself.
(Fil-C might be an interesting exception here, though IIRC its definition of memory safety is slightly different)
