- davrosthedalek 4mo agoHaven't looked at the code, but the allocated memory could be larger than necessary to make "off-by-one" or "off-by-a-few" errors less deadly. Then zeroing it out makes it even less so. Defense in depth. Or it's an allocation for an arena? The zeroing might help trigger 0 derefs earlier if the overrun happens for the object that are then allocated in the arena (and not by allocating more objects than the arena can provide)
- Shish2k 4mo agoThis doesn't prevent overrunning the buffer -- it means that when you do overrun the buffer, it does less damage
