Reduced test case

int vq_index(float *in, const float *codebook, int len, int entries)
{
   int i,j;
   int best_index=0;
   for (i=0;i<entries;i++)
   {
      float dist=0;
      for (j=0;j<len;j++)
      {
         float tmp = in[j]-*codebook++;
         dist += tmp*tmp;
      }
      if (i==0 || dist<0)
      {
         best_index=i;
      }
   }
   return best_index;
}
