12316	"ASIO: ""Undefined error: 0"" on the Mac OS 10.10 and 10.11"	David Dovodov <ddovod@…>	chris_kohlhoff	"Hello.
I have some issue with asio.
When I try to connect/read/write (blocking and async operations), i get ""Undefined error: 0"" in the boost::error_code parameter. Interesting thing is that data transfers successfully. Only problem is Undefined error and infinity reads with zero bytes read. iOS (device and simulator) has this error too.
If there's nobody listening on the port I try to connect to, ""Connection refused"" error is returned to the async_connect callback (which is correct behavior). So ""Undefined error: 0"" appears only if somebody is listening port on the other side.

Compiling with xCode and standalone clang with command like
clang++ -std=c++11 -Ipath/to/asio/include async_tcp_echo_server.cpp -oserver

There's an issue on the asio's github tracker, but there's no activity at all.
