#11915: Bug in xml_iarchive_impl<Archive>::load(std::wstring &ws)

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  serialization
  Version:  Boost 1.61.0      |   Severity:  Problem

------------------------------+---------------------------
 There is a problem when serialization calls
 {{{
 xml_iarchive_impl<Archive>::load(wchar_t * ws)
 }}}

 or

 {{{
 xml_iarchive_impl<Archive>::load(std::wstring &ws)
 }}}

 in Visual Studio VC 2010.

 When std::mbrtowc is called in this function needs that "std::mbstate_t
 mbs" must be initialized to "std::mbstate_t()" in its first loop.
 Current value is undefined in this platform because mbstate_t is only an
 int (typedef int mbstate_t). It should be initialized before you use.

 My proposed fix should be:

 {{{
 std::mbstate_t mbs = std::mbstate_t();
 }}}
