Comment (by jim.king@…):

 I can confirm this behavior in boost 1.62 as well:
 {{{
     //! Convert a string to a GUID
     inline GUID stog(const std::string& gs)
     {
         BOOST_STATIC_ASSERT(sizeof(GUID) == sizeof(boost::uuids::uuid));
         GUID result;
         memcpy(&result, boost::uuids::string_generator()(gs).data,
 sizeof(GUID));
         return result;
     }
 }}}

 Sitting in the debugger, we see I passed in an invalid uuid string but I
 got back a GUID that has FFFF in place of the "zzzz" I put in there:

 {{{
 +       gs                         "83f8638b-8dca-4152-zzzz-2ca8b33039b4"
 const
 +       &result 0x0000005305f9ed38 {8B63F883-CA8D-5241-FFFF-2CA8B33039B4}
 _GUID *
 }}}

 I would also like to see the parser here changed to be much more strict.
