Comment:

 I have been able to reproduce this with Visual Studio 2017 v15.5.5,
 compiler version 19.12.25835. The program fails to use the custom
 `operator<<` when compiled with this command line:

     cl /Od /MD /EHsc /I <Boost root> -c <source file>

 and succeeds when /Ob1 is added.

 Unfortunately, this is a compiler bug that I cannot work around in the
 library. Turning optimizations on or off definitely should not influence
 function lookup rules. I recommend you report this to
 [https://connect.microsoft.com/ Microsoft].
