--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Requires -fpie to reproduce.  Your testcase is compiled to

f:
.LFB0:
        .cfi_startproc
        pushl   %ebp
        .cfi_def_cfa_offset 8
        .cfi_offset 5, -8
        movl    %esp, %ebp
        .cfi_def_cfa_register 5
        call    __x86.get_pc_thunk.ax
        addl    $_GLOBAL_OFFSET_TABLE_, %eax
        movl    A@GOT(%eax), %eax
#APP
# 4 "t.c" 1
        movd (%eax) (, %edx, 4), %mm0

# 0 "" 2
#NO_APP


and appearantly your GCC distributor chose to enable -fpie by default.
