Hi Kaiyuan, I suspect you ran into this:
http://stackoverflow.com/questions/3025997/defining-static-const-integer-members-in-class-definition In opt and fast the values get inlined and we have no problem. In debug, they point to nothing since we do not have an out-of-class declaration. In fact we do this _a lot_. I think in this and many other cases, instead of adding out-of-class declaration, the most elegant solution is probably to embrace c++11 strongly typed enums. Could you perhaps give that a try?
