Worker A's two: the addition operand-order row (a1[i]+a0[i] vs a0[i]+a1[i] -- same length, 16 bytes apart, because cc1 evaluates the right-hand operand first) and the unconditional p[0]=0 that lands in a branch delay slot. Worker D's two: 0x8009B56C closed on cookbook 43 trigger 1 after D had nearly written the row off, and 0x80018458.
