Yes. It's either a bug in your code or in sws_scale. The fact that
ffmpeg doesn't reproduce it makes me lean towards it being a bug in
your code, but that doesn't necessarily mean it is. Or it's an
undocumented "feature" that needs to be documented.

You never mentioned which version of sws_scale/libav* you're using. If
you can reproduce it with the current git head and your code looks ok
(I can't see any immediate red flags from what little I've seen),
check out this page (also note the "Bug Tracker" sub section):
