--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC 4.1.2 produces:

foo:
        .long   25
        .zero   4
        .quad   __compound_literal.0
        .local  __compound_literal.0
        .comm   __compound_literal.0,0,8

While 4.4.7 (and above) produces:
foo:
        .zero   16=
