We don't have a C++ expert on hand, but taking a pointer to one member and expecting to access another by an offset is very fishy: - for one, there could theoretically be padding - the compiler might assume that we are only writing to that first member The new code has shown to be free for constant parameter values. Non-constant ones cause the assembly to have branches (why?), but we don't use that much.
