I would get a clearification from the standards comittee if I were you.  multiplying a large unsigned 
number by 16 and getting an overflow is werid case but again, the developer should be checking the 
size for reality, if they don't it can cause other problems like a seg fault as malloc on linux does not 
return null when running out of memory.
