malloc is not the only way for your app to leak memory. CGImage in particular allocates its own anonymous VM regions. footprint against your process (man 1 footprint) is a good way to get a quick look at where the system thinks this memory is going. Once you’ve looked at that, Instruments or vmmap or leaks is a good way to further refine your search.
