A malloc error usually means you have run out of memory: a memory
leak. It's hard to tell without analyzing the code, but you should
start by looking at the image created with "createSnapshot..."
because it follows the create rule for ownership which means you need
to release it.

I'm trying to render a frame sequence with QC offline but it dies
with a memory error after rendering some frames. My output is 720p
(1280 x720 30fps) and offline dies after rendering about 600 frames.
I've tried a few times and the error seems consistent. Not sure
where to start looking for the memory error.
Any siggestions?
