    Can't iterate empty stl list

    Problem resolved!
    Quite embarassing but:
    I forgot to allocate the Game instance
    m_pGame = new Game(); fixed it.

    I have a STL list which I know is empty, but I still do as always and write a for-loop that looks like this:
    typedef list<shared_ptr<Player> > PlayerList;
    class Game
    	bool Init(class NetworkManager* pNm);
    	bool Update(unsigned int deltaMilli);
    	void OnClientConnect(shared_ptr<class Socket> pSocket);
    	PlayerList m_Players;
    bool Game::Update(unsigned int deltaMilli)
    	for (PlayerList::iterator i = m_Players.begin(); i != m_Players.end(); ++i) //Crash!
    	return true;
    At the line commented crash, the application crashes due to memory access violation in the list. I have used similar code many times before with sucess and I am very confused why this isn't working anymore. I have also tried with a vector and the same results showed up.

    Error message:
    Unhandled exception at 0x0000000140014c65 in Application.exe: 0xC0000005: Access violation reading location 0xffffffffffffffff.
    I have no compilation warnings, but this linker warning:
    1>LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library
    The project is built under 64-bits debug mode.

    Would really appreciate some help on this tough one as I am completely clueless.

    Thanks in advance
