---------------------------------------+------------------------------------
 The boost::asio sockets streams classes derive from std::basic_iostream,
 and then call {{{tie(this)}}}] in the basic_socket_iostream constructor.

 In C++11 this is no longer legal (I tried providing a link here, but trac
 wouldn't let me). The issue is explained here: {{{cplusplus.github.com/LWG
 /lwg-defects.html#835}}}

 Some standard libraries (like libc++) already implement this behavior, and
 so attempts to use the ASIO socket streams classes cause infinite
 recursion leading to eventual stack exhaustion and a crash.

 I found this issue in boost 1.50.0, but it appears on the boost trunk svn
 as well so I have filled the ticket against trunk.
