13564	Compile error of asio::async_read_until	Vincent Lextrait <vincent.lextrait@…>	chris_kohlhoff	"I have a new compile error after moving from asio in 1.65.1 to asio in 1.67.0. Same code which compiled fine before.
async_read_until uses read_until_delim_string_op in read_until.hpp, and the ctor has been rewritten in 67.0. It seems to want now to copy the buffer in the first constructor. Buffers are non copyable, so there is a compile error.

The 67.0 ctor is now a template:

    template <typename BufferSequence>
    read_until_delim_string_op(AsyncReadStream& stream,
        BOOST_ASIO_MOVE_ARG(BufferSequence) buffers,
	const std::string& delim, ReadHandler& handler)
      : stream_(stream),
        buffers_(BOOST_ASIO_MOVE_CAST(BufferSequence)(buffers)),
        delim_(delim),
	start_(0),
        search_position_(0),
        handler_(BOOST_ASIO_MOVE_CAST(ReadHandler)(handler))
    {
    }

In 65.1 the ctor was:

    read_until_delim_op(AsyncReadStream& stream,
        boost::asio::basic_streambuf<Allocator>& streambuf,
        char delim, ReadHandler& handler)
      : stream_(stream),
        streambuf_(streambuf),
        delim_(delim),
        start_(0),
        search_position_(0),
        handler_(BOOST_ASIO_MOVE_CAST(ReadHandler)(handler))

I have gcc 8.1.
Not sure if this is a bug (it sounds like it), therefore logging this as ""Support Request"" for now."	Bugs	new	To Be Determined	asio	Boost 1.67.0	Problem
