My guess is that you're just forcing the alloc & memcpy immediately instead of having it postponed like it is currently (the filter holds a reference to that frame). So you probably basically just hit your memory limit at a different time, and just have another weird crash, I guess? Maybe somewhere we're just missing a malloc check or something.
