Thanks for the explanation. In that case I won't open a bug since
- as you point out fedora does not use the bytecode interpeter by
default
- I'm pretty sure this will be taken care of with time. Hinting always
lags a bit behind glyph design, so probably the letters you point where
tweaked in the last release and the dejavu hint master haven't got the
time to re-hint them yet.

But I'll CC this mail to the team just in case
