Most of those are issues in old, _C_ code. No one disputes the fact that C is a mine field due to its complete lack of support for things like arrays and strings.

But that's not really an issue in modern C++. It's only really a problem when you want to implement your own data structures with raw pointers, in which case, yes, you have to be careful and write tests and use sanitizers, Valgrind, etc.
