> i don't know in which reality you live but in mine there's not much relationship between the existence of crashes, and them being resolved during development Really? Crashes during development are the easiest thing to resolve aren't they? Your debugger gets triggered automatically. In my experience crashes are treated as highest priority. > i don't even know what to say. that's the whole point of destructors - you know that things will be unwound in the reverse order from which they were created on automatic storage. that's, like, why c++ exists Have you met my friend the virtual keyword?

> Really? Crashes during development are the easiest thing to resolve aren't they? sure but here we're talking about the edge cases which you won't encounter during development. e.g. imagine you're writing a 3D .obj parser and someone somewhere uses a mesh which for some reason has a NaN instead of a real value somewhere, and your parser parses it and gets a NaN into your system - you'll only encounter the subsequent crashes if your tests had expected such a thing. now multiply this by infinity - it's impossible to think of everything beforehand. But you really don't want the person to crash their 3D software because of that invalid .obj file, just to show them a pop-up "the mesh could not be loaded" and roll-back to before the loading was attempted. > Have you met my friend the virtual keyword? .. what about it ? compilers warn you when you forget it if you aren't using GCC 2.95. https://gcc.godbolt.org/z/d4Yj9z3zf https://gcc.godbolt.org/z/d4Yj9z3zf This hasn't been an issue for more than a decade. clang 3.0 (2011) and gcc 4.1 (2007) already warned for this (and there aren't older compilers on CE that I can test). There are people who start learning programming today who weren't even born when GCC implemented this FFS
