resize memory leak (minor)

edit

I found a small memory leak through valgrind. I comes from the resize function. This is the simplest code generating it:

    cv::Mat f_out, f_in= cv::Mat(100, 100, CV_8U, 1); // nrows, ncols
    cv::Size c_size(200, 200);
    cv::resize(f_in, f_out, c_size, 0, 0, cv::INTER_LINEAR);

OpenCV is 3.0.0; the system is Centos 6.0;, with gcc 4.47 and glibc version 4.4.7 20120313 (Red Hat 4.4.7-11). I tried playing with it:

int main(int agrc, char** argv)
{
    int kk=10000;
    for (int k=0; k<kk; ++k)
    {
        int tt=(int) (300 + 100*sin(0.0001*k));
        int vv=(int) (3 + 1*sin(0.0001*k));
        cv::Mat f_out, f_in= cv::Mat(tt, tt, CV_8U, vv); // nrows, ncols
        cv::Size c_size(tt/2, tt/2);
        cv::resize(f_in, f_out, c_size, 0, 0, cv::INTER_LINEAR);
    }
return 0;
}

and I still get exactly the same 288 bytes reported as "still reachable" by Valgrind:
