Oh yes, all our checkers are developed upon user request. They only request it if they find out their developers write such silly code. And this kind of bug is nasty to debug. (In case of addition less memory is available behind the pointer while the memory ahead of it is lost. In case of subtraction data before the pointer gets overwritten.)
