We can all agree it's not medical systems, but audio DSP and game dev both end up rewriting a lot of STL stuff to suit their needs, and often using a restricted subset of modern C++ features for similar reasons.
That isn't some arbitrary choice, but pretty much where everyone continually ends up when solving real-time problems using C++. Whether those be games or not.
You can prevent more than enough crashes with enough testing to make gamers happy. Even if you prove there is not out of bounds error I still want a medical device to check
