Reduced testcase:
double bessel_Kn_scaled_small_x(int n, double x)
{
  int k;
  double y = 0.25 * x * x;
  double ex = exp(x);
  double k_term;
  double term1, sum1, ln_pre1;
  double term2, sum2, pre2;
  for(k=1; k<=n-1; k++)
  {
    k_term *= -y/(k * (n-k));
    sum1 += k_term;
  }
  term1 = 0.5 * exp(ln_pre1) * sum1;
  return ex * (term1 + term2);
}
