I have no idea what might be causing this. I think it only can be resolved if Mo Jia actually researches the errors himself. Mo Jia, pick one particular error, and stick to it until you completely understand it. If you cannot do this, we may have to wait until somebody else shows up who can reproduce the problem, and also analyze it.

For example, for the original problem, we would need the original command line that compiled b_print.obj, and check whether /GS was passed to that compilation command or not.
