I don't know what you intend to do with that string, but if
all you need is a buffer of chars which frees its own memory automatically,
then I usually use vector<char> of vector<int> or whatever type
of buffer you need.

With v being the vector, it's guaranteed that &v[0] points to
a sequential memory which you can use as a buffer.
