Even if you are sure that your 'known' memory leak will not cause havoc, don't do it. At best, it will pave a way for you to make a similar and probably more critical mistake at a different time and place.
For me, asking this is like questioning "Can I break the red light at 3 AM in the morning when no one is around?". Well sure, it may not cause any trouble at that time but it will provide a lever for you to do the same in rush hour!
