> Converting the legacy code base (490,000 lines of code) to C++ was a straightforward, mechanical task that took only a couple of hours That sounds like they haven't actually converted it to C++ so much as compiled it as C++. That means they're probably still using raw owning pointers and no RAII, which means you get none of the safety benefits of C++ (which do exist, so long as you use modern C++ practices like smart pointers, and containers instead of C-style arrays).
