Comment (by Kamedo2):
Klaussfreire, sorry for the slow response.
Yes, the assertion error only happens when the {{{-aac_coder}}} is
{{{anmr}}}.
FFmpeg_anmr_error6 and FFmpeg_anmr_error7 crashes at the beginning of the
file, but I've found 4 music tracks (out of hundreds) that crashes at the
middle of the file.
I failed to reproduce the results after cutting to distributable short
clips.
Also I have listened to hundreds of songs encoded by v9b {{{anmr}}} and
{{{twoloop}}} and I have found no apparent problems so far.
