I know that the string is allocated by the constructor

String ctors are handled specially by the runtime, since the size of
which needs to be allocated is dictated by the parameters of the ctor, so we
can't do the usual 'allocate an object, then call its ctor' stuff, the
has to allocate the string object. This is why these ctors are implemented
