    12.2  Temporary objects                            [class.temporary]

2   When  a compiler introduces a temporary object of a class that has a
    non-trivial constructor (_class.ctor_), it shall ensure that a  con-
    structor  is  called  for  the  temporary  object.   Similarly,  the
    destructor shall be  called  for  a  temporary  with  a  non-trivial
    destructor   (_class.dtor_).    Ordinarily,  temporary  objects  are
    destroyed  as  the  last  step  in  evaluating  the  full-expression
    (_intro.execution_)  that  (lexically) contains the point where they
    were created.  This is true even if that evaluation ends in throwing
    an exception.
