Probably fallout of the DECL_NONALIASED "hack". We likely have to restrict vectorizing / IVOPTing those. Basically we want to be able to apply store motion to counter updates which means we have to be able to disambiguate counter loads/stores against other memory accesses. I'll see what exactly happens here (just guessing above).
