Comment (by klaussfreire):
Sorry for the silence, the assertion error has been fixed already. Some
bug I couldn't find with encode_window_bands_info, but I just made anmr
use the other (codebook_trellis_rate? something like that) which is very
similar but better (avoids adding holes or picking a codebook that cannot
encode the coefficients, for instance).
I'm currently doing a frankenstein between v9 and v7, to get v9 close to
v7 in stability only with better quality. I'm close to posting v9b,
hopefully a version that can be sliced and committed (if v7 was acceptable
v9b should be as well)
