I have a very similar problem in my program. It segfaults in this instruction:
0x0815935d <vector+203>: movapd %xmm0,(%eax)
where I have
eax 0xbfffd874 -1073751948
and
(gdb) p ((unsigned int)0xbfffd874)
$1 = 3221215348
(gdb) p ((unsigned int)0xbfffd874) % 16
$2 = 4
So indeed movapd isn't writing to 16-byte aligned storage.
