This is not useful as a benchmark.
Reduced test case:

void test5845(ulong cols) {}

uint solve(bool niv, ref ulong cols) {
    if (niv)
        solve(false, cols);
    else
        test5845(cols);
    return 65;
}

ulong nqueen(int n) {
    ulong cols    = 0;
    return solve(true, cols);
}

static assert(nqueen(2) == 65);
