Yes, replacing '-f segment ....' with '-f mp4 foo.mp4' works correctly.

Yes, it fails with all video sources I tried where the output c:v is
libx264, or c:v is copy and source is h264 (see below).

ffmpeg -i /tank/video/scratch/ashes_05_match_4.2.5mb.mp4 -r 25 \
    -c:a libfaac -ab:a 128k -ac:a 2 -c:v copy -threads 0 -map 0 \
    -f segment -segment_time 10 -segment_list test.m3u8 \
    -segment_format mpegts stream%05d.ts
