As you can see, this function also has overloads that take
boost::system::error_code by reference:
http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/ip__address/from_string.html

Generally, if a function in asio has overloads with and without such a
parameter, the former "returns" an error in the parameter, and the
latter throws boost::system::system_error instead.
For most functions it's mentioned explicitly, like here:
http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/basic_stream_socket/connect/overload1.html

But from_string() reference really lacks this point for some reason.
