Apart from -DDEBUG the extra -g is the only difference I have spotted in

Ok, i'm just an idiot. totally forgot that an assert evaluates to
nothing on a non debug build.
A fix is checked in, so please try again.
Working now without debug.
I notice there are some extra artifacts on the pendulum stream now in
the form of blocks around the coloured circles.
You can also see some artefacts on "large" (at least 8x8 pixel) areas of
black going into bright colours with sharp edges. I think that is either
because of signed normalized 16bits aren't precise enough to calculate
the idct or because of the missing clamping on non intra frames.
Actually in the case of pendulum, what I saw as artifacts are in reality
small areas of correctness where black/white are rendered properly as 0/255.
Compared to pre-idct, idct is mostly not rendering black or white
correctly. The (HD) test stream -

Looked OK before idct but is quite wrong now.
