No, it's Microsoft and CrowdStrike's fault. People are always quick to make it C++'s fault; from what I've read so far, it's the lack of tests, engineers being lazy, and also the need for more performance that made them hand-craft stuff instead of using battle-tested utilities.

Look, we can now set a breakpoint in our code in C++26. No compiler yet supports this, but it shouldn't be hard to implement since all of them support some custom way of doing this already; like __builtin_debugtrap in llvm. JavaScript has similar thing too.

Be aware of using <ranges> in performance issues. This simple snippet, produces different assemblies for -Os, -Og, -O0, -O1, -O2, and -O3 flags. Ranges relies too much on the compiler's optimizer. Don't use ranges where you can't have a "wildcard" to play a role in performance.
