    Hmm, this seems a bad sequence, movaps can't have repnz prefix,
    since movaps is not string operation... It might happen since
    AVX opcodes supporting processors are not released yet.

    Anyway, I think we'd better change the posttest to report it
    as warning instead of errors.

    Thank you,
