Replying to [comment:5 jstressman]:
> So the bug we're seeing in the preview could be an example of it running
out of space and just repeating what part of it it did manage to fit in
memory or something? And like you said, something likely with libjpeg
itself, as the exact same thing shows up in ShowImage.
Right now it's merely conjecture as a possibility because of the sheer
size of the image involved. 700MB shouldn't be big enough to be triggering
any integer overflow errors or anything in that vein so memory consumption
just seems like the most probable culprit. One commonality between
ShowImage and Backgrounds is that they both go through the JPEG
translator, which could well be masking/mishandling an error return from
libjpeg resulting in the behavior above. WebCore on the other hand uses
libjpeg directly so the issue there might be a bit different but still
related. Would need some more investigation to be certain.
