Re: [Boost-users] boost::bind - What if bound (method, instance) doesn't exist anymore?

What happens when a boost::function is called and has been created with a (method, instance) combination, but the instance no longer exists?

What happens when this is in combination with boost::asio::io_service?

Here is my suspect code:

B::SharedPtr me = boost::dynamic_pointer_cast<B, A>(shared_from_this()); callback = boost::bind(&B::Foo, me, boost::asio::placeholder::error);

// this is a boost::asio::ip::tcp::acceptor acceptor.async_accept(socket_, callback);

Now suppose I use a raw pointer instead. Now suppose the instance that just got bound was destroyed before the accept happened.

What will be the result?

Crash (access violation / segfault).
