Well - that's because values_ may point to *this and thus



                                au::BoundBit< 7 >( values_[ index ] ) = 1;



may alter it.  Remember values_ is a pointer to char *.



So it's not valid for GCC to CSE the load of values_ which means the

stores are not detected as redundant.
