I think that this is a tiny bit too pessimistic.

It is possible to write portable C++ code that uses malloc() and
friends -- all without knowing what the underlying implementation
does.  If you follow the rules, your code will be completely
portable.  I would submit that it's not even that difficult to do
this.

malloc() and free() and new and delete etc. all do what the standards
say they should do.  As long as you use these things as they are
intended, your code will be fine.
