    Yeah, this particular one really should only bite you with

    The SG code potentially _derefences_ a field past the end of the SG array,
    but it should be a read, and the result should never be used (it's used to
    calculate the pointer to past the end of the queue, so if it's used,
    there's another bug lurking).

    Please do. I wouldn't be surprised if it's also related to the SG changes,
    but I don't think it's the exact particular bug that Ingo saw.
