This seems to break fate-prores-422 and fate-prores-422_hq on my laptop (OS X
64 bit with gcc 4.2.1). But if built without optimizations, it works. The
fate configuration that is similar to this seems to work though.
If I comment out the dct_permutation array, it works. Does this indicate it
might be some overread somewhere? Also, if I disable using
ff_prores_idct_put_10_sse2, it also works.
I'm not able to reproduce this any longer. Either something in my build
was broken, or it's a heisenbug.
