我正在使用Valgrind检查内存泄漏。
不幸的是，我收到4警告。
附加的是我的代码的简化版本，它再现了错误：
Leak_DefinitelyLost丢失发生在#include <iostream>
#include <vector>
#include <memory>
#include <unordered_map>
using namespace std;

public:
explicit Base(double a){
a_ = a;
}

int main() {

if(i%2 == 0){
vector<double> b{1., 2., 3.};
vector<double> c{4., 5., 6.};
o = make_unique<Derived_A>(i, move(b), move(c));
m[to_string(i)] = move(o);
}else{
double b = 1.;
double c = 2.;
o = make_unique<Derived_B>(i, b, c);
m[to_string(i)] = move(o);
}
}
for(const auto &any:m){
any.second->fun();
}
return 0;
}
通话期间：
make_unique我不确定自己在做什么错。有人可以澄清错误发生的地方吗？
（我从CLion 2018.1.5，Valgrind 3.13.0中呼叫Valgrind。）
