Why are you calling 'arr.data()' if it's to do nothing with the returned ptr?

I've tried this in Qt 4.5.1:
====
int main(int /*argc*/, char ** /*argv*/)
{
        QByteArray a;
        a.resize(0);
        a.data();
        qDebug("size of a: %d", a.size());
        return 0;
}

and the result is:
 => size of a: 0
