I think this is your problem...

[...]
  for (i=0; i<n; i++)
    {
      unsigned int k = double gsl_rng_uniform_pos (const
                               ^^^^^               gsl_rng*r);

I think you meant to cast it from a double to an int...like

unsigned int k = (double) gsl_rng_uniform_pos (const gsl_rng *r);
