Yeh, it's a bug in Valgrind's SSE instruction decoder, which causes it to
read 128-bit chunks from memory when in fact it should only be reading
64-bits.  Well spotted.  You can cancel the gcc bug.  I'll contemplate a fix.

   0x400862:  cmpsd $2,(%rsi,%rax,8),%xmm3

      ------ IMark(0x400862, 6) ------
      PUT(168) = 0x400862:I64
      t8 = Add64(GET:I64(48),Shl64(GET:I64(0),0x3:I8))
      t7 = CmpLE64F0x2(GET:V128(248),LDle:V128(t8))
      PUT(248) = t7                  ^^^^^^^^^^^^^ 128-bit load
