indeed. Using free() on a piece of memory allocated by new is rather
dangerous, you have no idea what the C++ library is doing behind the scenes.
Plus as Shyamal points out, none of the destructors that should be called
would be. Just because malloc() happens to be the deep, deep implementation
does not mean there is not useful and important code inbetween.
