Comment (by igaztanaga):

 Thanks for the report. It seems that it is a compiler bug, and standard
 libraries before Visual 2013 used some dummy virtual functions in
 basic_istream and basic_ostream to fix it. Starting with Visual 2013
 <istream> and <ostream> contain a pragma to fix the bug with the comment:

  #pragma vtordisp(push, 2) // compiler bug workaround

 The fix is to use the same pragma when forward declaring the basic_istream
 and basic_ostream.

 Thanks a lot for the detailed report and MSVC solutions, they helped a
 lot.
