Review comment:
I've created small test to simulate our situation
```
#include <memory>
#include <iostream>
using namespace std;
class Ctx {
public:
~Ctx() {
cout << "destroyed";
}
};
class Wrapper{
public:
Wrapper() {}
Wrapper(shared_ptr<Ctx> pCtx_): pCtx(pCtx_) {}
private:
shared_ptr<Ctx> pCtx;
};
class Env {
public:
Env(shared_ptr<Ctx> pCtx_): pCtx(pCtx_) {}
void AddWrapper() {
cout << "Num references before setting wrapper " << pCtx.use_count()
<< endl;
this->wrapper = Wrapper(pCtx);
cout << "Num references after after setting wrapper " <<
pCtx.use_count() << endl;
}
private:
shared_ptr<Ctx> pCtx;
Wrapper wrapper;
};
int main() {
auto pCtx = make_shared<Ctx>();
cout << "Num references before assignment " << pCtx.use_count() << endl;
{
Env env(pCtx);
env.AddWrapper();
env.AddWrapper();
}
cout << "Num references final " << pCtx.use_count() << endl;
return 0;
}
```
Num references before assignment 1
Num references before setting wrapper 2
Num references after after setting wrapper 3
Num references before setting wrapper 3
Num references after after setting wrapper 3
Num references final 1
destroyed
```
