[Boost-users] [asio] endpoint lifetime requirements with acceptor

Subject: [Boost-users] [asio] endpoint lifetime requirements with acceptor

What is the lifetime requirement of a boost::asio::ip::tcp::endpoint 
imposed by boost::asio::ip::tcp::acceptor. in particular it's ctor: 
boost::asio::ip::tcp::acceptor(boost::asio::io_service& io_, const 
endpoint_type&, bool);

The end point is taken by const&. Is it just used, copied, or does the 
acceptor hold a const&? Are these sorts of issues documented? The only 
clue I can find is that the endpoint has a copy ctor.

I can successfully construct the acceptor, passing in a temporary 
endpoint which is constructed in place in the acceptor's ctor, which 
appears to execute on both Win/MSVC8 and Mac/XCode3.2. But if I 
construct an endpoint further up the call stack passing it by const&, I 
get a runtime error.

Any help appreciated.

Thanks, Jeff
