I used the ISO standard of the version of C++ I was using (17 or 20, dont remember) to look up how variables are initialized if they arent explicitly initialized, and it turns out the standard has a very clear definition of e.g. variables in a function which are of a class type have their default ctor called, or something like that. So it was very successful. No idea what your UB rant is about.
