No, the issues I had were specifically with using core image filter and feedback. I didn't try the feedback patch back then, but every other method led to a massive memory leak. It didn't affect the accumulator so far as I know.
I'm using the feedback patch at the moment, with *massive* volumes of image data. Over 400,000 images have passed through it without any noticable leaking. This is feeding glsl though, not core image.
