This is in 'partial_stride' handling at the 'movaps' instruction:
11: 48 89 d0 mov %rdx,%rax
14: 48 c1 e0 04 shl $0x4,%rax
18: 48 81 c7 80 00 00 00 add $0x80,%rdi
1f: 48 29 c7 sub %rax,%rdi
22: 0f 10 06 movups (%rsi),%xmm0
25: 66 41 0f ef c7 pxor %xmm15,%xmm0
2a:* 0f 28 0f movaps (%rdi),%xmm1 <-- trapping instruction
