--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Is gcc warning about t being set but unused? If so then the warning is correct "t =" is just setting t and the variable is otherwise unused and can be removed as it has no side effects. *(&t) disables the warning as &t is using t for its address.
