Comment (by Niklas Haas):
I can't reproduce this on current git master (a3ca4beeaa4). In particular,
every commit since d119ae2fd82a4 fixes the output for me:
$ git checkout d119ae2fd82a4 && make
$ ./ffmpeg -y -i src.mp4 -filter_complex "[0:v]trim=start=0.5:end=0.9[v];
[0:a]atrim=start=0.5:end=0.9[a]" -map [v] -map [a] out.mp4
