 Reporter:  anonymous     |       Owner:  ramey        
     Type:  Bugs          |      Status:  new          
Milestone:  Boost 1.40.0  |   Component:  serialization
  Version:  Boost 1.39.0  |    Severity:  Problem      
 Keywords:  wchar_t       |  
--------------------------+-------------------------------------------------
 basic_binary_iprimitive<Archive, Elem, Tr>::load(wchar_t * ws)
 {
     std::size_t l;

     this->This()->load(l);

     load_binary(ws, l * sizeof(wchar_t) / sizeof(char));

     ws[l / sizeof(wchar_t)] = L'\0';
 }

 l is determined by std::wcslen on saving, which returns the number of
 wchar_t characters in the string. not the length in bytes.
 the \0 insert treats l as it was an offset in bytes.
