--- Comment #17 from Uroš Bizjak <ubizjak at gmail dot com> ---
The asm dump claims that the access is aligned to 32bytes:

#(insn 14 31 9 2 (set (mem:V4DI (plus:DI (reg/f:DI 3 bx [orig:90 this ] [90])
#                (const_int 64 [0x40])) [6 MEM[(long unsigned int *)this_6(D) +
64B]+0 S32 A256])
#        (reg:V4DI 21 xmm0 [92])) "../../src/stateful_rx_core.cpp":254 1228
{movv4di_internal}
#     (nil))
        vmovdqa %ymm0, 64(%rbx) # 14    movv4di_internal/4      [length = 5]


which gets expanded from:

;; MEM[(long unsigned int *)this_6(D) + 64B] = { 0, 0, 0, 0 };

(insn 13 12 14 (set (reg:V4DI 92)
        (const_vector:V4DI [
                (const_int 0 [0])
                (const_int 0 [0])
                (const_int 0 [0])
                (const_int 0 [0])
            ])) "../../src/stateful_rx_core.cpp":254 -1
     (nil))

(insn 14 13 0 (set (mem:V4DI (plus:DI (reg/f:DI 90 [ this ])
                (const_int 64 [0x40])) [6 MEM[(long unsigned int *)this_6(D) +
64B]+0 S32 A256])
        (reg:V4DI 92)) "../../src/stateful_rx_core.cpp":254 -1
     (nil))

So, not a target issue.
