```cpp
#include <map>
#include <tuple>
int& reproduce(int Key) {
std::map<int, int> Cache;
std::map<int, int>::iterator It = Cache.begin();
bool New;
std::tie(It, New) = Cache.try_emplace(Key);
return It->second;
}
```
`std::tie` on LHS should KILL the iterator `It` value and therefore it shouldn't be considered alive at the point of invalidation.
