GCC still considers an automatic variable that doesn't have an explicit -initializer as uninitialized, -Wuninitialized will still report warning messages -on such automatic variables. +initializer as uninitialized, @option{-Wuninitialized} will still report +warning messages on such automatic variables. With this option, GCC will also initialize any padding of automatic variables that have structure or union types to zeroes.
