```
#include <algorithm>
#include <vector>
int* ptr;
auto test1(std::vector<int>& v, int n) {
ptr = new int;
return std::find_if(v.begin(), v.end(), [n](int v) { return v < n; });
}
auto test2(std::vector<int>& v, int n) {
return std::find_if(v.begin(), v.end(), [n](int v) { return v < n; });
}
```
should generate the same code for both functions except for the additional allocation in `test1`. However, one seems to be unrolled, while the other gets vectorized.
