Yeah, this particular one really should only bite you with DEBUG_PAGEALLOC. 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). > Then something else is broken, perhaps.

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.
