    Sample FFT_Kernels.cl in SDK 2.9-1 opencl/cpp_cl/FFT is broken

      void FFT::Init(__global float *real,__global float *imag,__local float *Localds)
      {
           gr = real;

           gi = imag;
           lds = Localds;
           gid = get_global_id(0);
            me = gid & 0x3fU;
            dg = (gid >> 6) * VSTRIDE;
            gr += dg;
            gi += dg;
      }

       

      In the host program globalThreads[0] = 64. Therefore, dg (the mp step) is always 0. As a result, it runs the full 64x1024 FFT each time, overwriting previous results. I am sure this is not intentional. Plz fix.
