----------------------------------+-----------------------------------------
 following app crashes on VC10 (Windows 7) (multibyte and Unicode builds)
 at point of creation of path (im working around the issue by
 doing dummy string to wstring conversion)
 [
  wstring r; std::copy(s.begin(),s.end(),r.begin());
