Frankly speaking, I have not stumbled upon this bug in real life --- just done
some FS fuzzing and for improving performance used smaller FS images. Maybe
smaller images have larger probability of triggering some bugs in my setup, too
(now I know why :) ). But inline_data (as well as other extended options) were
enabled deliberately, of course, supposing they are less stable than the core
features.
