--- 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.
