90or need to use a function with less aligned data then send a mail to the ffmpeg-dev list, ...

92!warning these alignments might not match reallity, (missing attribute((align)) stuff somewhere possible)
93i (michael) didnt check them, these are just the alignents which i think could be reached easily ...
