Even modern C++ isn't memory safe. Most straightforward example is to move a uniq_ptr, which makes it a nullptr, ready to be dereferenced and cause UB.

How does it happen? Non-const unique_ptr& used as a function parameter?

I can simplify your example:

  unique_ptr<int> p;
  auto n = *p; // C++ kills!
