[Boost-users] Safe to pass dereferenced anonymous shared_ptr?

Q1: Is the below code dangerous? A1: Only if the anonymous shared_ptr is deleted before function f returns. Q2: Is the anonymous shared_ptr deleted before function f returns? A2: ? Thank you, Chris === #include <iostream> #include void f(const int& i) { std::cout << "i = " << i << std::endl; } int main() { f(*boost::make_shared<int>(42)); return 0; }
