I have a simple program with a memory leak that is driving me crazy.
It's basically a slide show application (no I can't use IKSlideShow),
where I repeatedly set an image in a CALayer. When run, the app
increases in memory size by 10MB or so every time a new image is
displayed.

This is NOT evidence for a leak. Do not attempt to second-guess that Mac OS
X virtual memory management system. In fact, do not guess. The only way to
know whether you have a leak is to use the memory analysis tools
(MallocDebug, Shark, what have you). m.



I have used ObjectAlloc and MallocDebug. In ObjectAlloc you can see the graph of memory usage go up like a stair-step ad infinitum. If I leave the program running long enough it crashes after running out of memory. Both programs show large memory usage from CGSImageDataLock- >img_data_lock (deep within a CATransactionCommit inside the runloop). That doesn't really help me though.
