Comment (by ramey):

 OK, I've got you sucked into the maelstrom.

 Here's some information about text_wiarchive.

 Both the xml_wiarchive as well as text_wiarchive depend on codecvt facets
 to read characters.  the xml one depends on utf8_codecvt where as the text
 one depends upon codecvt_null.  This might be an important distinction.

 The program throws an exception in basic_text_iprimitive.hpp:86 .  This is
 sort of interesting since the same module is used by both xml and text
 archives. Again this points to codecvt facet.  Clearly, the statement at
 basic_text_iprimitive.hpp:84 is returning false or zero.

 What I would suggest is to use the debugger to set a breakpoint at
 basic_text_iprimitive.hpp:84 and then start stepping into the code.  This
 should reveal what is happening.

 If you want to know what should happen, you could run the xml_wiarchive
 version of the test, set the same breakpoint and step into the code there.

 The difference between the two code paths should reveal the source of the
 problem.

 Thanks in advance for your help in this matter.  Addressing this issue
 would make the test matrix for the serialization library almost all green.
