I've now reproduced this error with the current git-head
(N-44711-gf25d53d) on 2 different computers and different Distros
(Debian 6.0.3/Ubuntu 11.10). Behavior is consistent, so I assume my test
is correct.

Can anyone else confirm this?


Additionally, I've now ran the tests with slice-count iterating from
2-70 (Yes, I know that only some of these values are valid, but that was
the fastest way to check if other slice-count numbers are affected, too)

The slice-count numbers producing broken slices for
"bride_close_cif.y4m" are:
24, 30 and 56.

@Michael:
Is there anything I should check?


Thanks,
