[Method]

Yes, i am sure(within reasonable doubt).

It works for a few iterations before failing.
I had the 2 other team programmers look to check that everything was alright when this issue started (after I added code using those lines).

The CPU usage in the DS climbs when it starts using the camera and plateaus for a while while it works before stopping.

I could post before and after code if it would help. (this is reasonably short because it's simplified and camera-specific)

I delete everything I use in any loops which I make it in.
