Why do some submissions get AC in Original constraints but WA in subtasks.

I have seen quite a few no of problems having submissions which have passed original constraints but not the subtasks ( like this ) . I think something needs to be done about such submissions since I am pretty sure the authors would want such subs to give WA. I suggest codechef should enable a feature which gives points for original constraints only if all subtasks get AC or make the test cases stronger (ahem ahem) ,

Another example : .

It could happen just because of boundary cases
