constructor

Could you tell me what is wrong with my class constructor? Code:

CVector::CVector (int size_)
{
    if (size_ > 0)
    {
        this->size = size_;
        this->data = new double[size];
        for (int i = 0; i < size; i++)
        {   
            (*this)(i) = i;
        }
    }
    cout << "constructor end" << endl;
    return;
}

Usage example:

tvector = CVector(6);

I get an access violation after "constructor end" output.
