Changes (by anonymous):

 * version:  Boost 1.62.0 => Boost 1.64.0

Comment:

 With 1.64 it is still there.
 Has it some priority? Or it will be gone with static inicializing thread-
 safe compilers (I use MSVC 2013, which is probably not)?

 {{{
 Unhandled exception thrown: read access violation.
 _Loc._Ptr was nullptr.
 }}}

 Incriminated thread (optimized code):

 {{{
         [Inline Frame] My.dll!std::locale::_Getfacet(unsigned __int64)
 Line 468
         My.dll!std::use_facet<std::codecvt<wchar_t,char,int> >(const
 std::locale & _Loc) Line 572
         My.dll!MyCode() Line 692 // calling boost::filesystem::path(const
 std::string &)
 }}}

 I also suspect path_locale(), where is static inicializing global shared
 object across threads.
