Considering that Chromium, being one of the most heavily statically analyzed code bases, is full of commits which fix memory leaks, your comment makes absolutely no sense.
Chromium is a massive project spanning decades of intense active development that intricately connects just about every domain of programming.
A few leaks fixed per month is nothing. Further there is no major language promising no leaks once you include things like retained references to garbage and reference cycles. Leaks are one thing modern C++ solves pretty well.
It's a bit hard to get an overview. But I did spot several uses of owning raw pointers and switching from those to managed ones. I'd say that's exactly the point I was trying to make.
