Reduced testcase:
```
double Test(int p, double *sum3, double *sum4, double *wX) {
    double tmp;
    double bS1 = 0.;
    double bS2 = 0.;
    for (int i = 0; i < p; ++i) {
      tmp = wX[i] * wX[i];
      if (tmp != 0.0) {
        bS1 += sum3[i] * sum3[i] / (tmp * wX[i]);
        bS2 += sum4[i] / tmp;
      }
    }
    return (bS2 + bS1);
}
```
