I found that 32-bit total_error_* variables in fixed_compute_best_predictor() functions can overflow. For example it happens with the attached test.wav and the following options: "-l 0 -b 4200 -m -r 5". The attached patch should fix it. (Now all three use_wide_by_* variables are unused, so I commented them out with #ifdef 0). -------------- next part -------------- A non-text attachment was scrubbed...
