Actually, a middle-end problem, if at all. With -ftree-ter, expand creates a
couple of unaligned loads to arg0:

(insn 101 100 102 (set (reg:SI 150)
        (mem:SI (reg/v/f:DI 115 [ arg0 ]) [0  S4 A8])) scope-reduced.c:60 -1
     (nil))
...
(insn 105 104 106 17 (set (mem:SI (reg/v/f:DI 115 [ arg0 ]) [0  S4 A8])
        (reg:SI 151)) scope-reduced.c:60 -1
     (nil))
