 Setup: Windows 7 x64, FFMPEG g08781ebe1-2024-04-29 x64

 Source: song.dsf https://fastupload.io/en/8hp1Dg1K3KNY3Zc/file

 Command: ffmpeg -i song.dsf -af
 "volume=6dB,aresample=96000:resampler=soxr:precision=28:osf=s32:dither_method=triangular_hp,acrossover=24000:order=8th[low][high];[low]anull;[high]anullsink"
 out.flac

 When the encoding is almost done, the red line appears. It says “Assertion
 best_input >= 0 failed at fftools/ffmpeg_filter.c:2075”. Then I see a GUI
 window that says “ffmpeg.exe has stopped working” with a button “Close the
 program”. An incomplete FLAC file remains on the disk, i.e. flac -t
 song.flac says “FLAC__STREAM_DECODER_ERROR_STATUS_LOST_SYNC” and “
 FLAC__STREAM_DECODER_END_OF_STREAM”. If I remove that acrossover filter,
 then the encoding goes fine.
