Comment 35 for bug 1608180

OK, sounds like a plan. One thing you might want to do is instead of grepping for "movd 0x108(%rdi,%rax,4),%xmm4" (that is, 66 0f 6e a4 87 08 01), grep for actual opcodes of the faulty instruction (I originally did not use it because I didn't know exact opcode string, but "disas /r" from new gdb should give you both the opcodes and mnemonics).
