It sound as if this issue's description matches your observation:
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-June/212757.html

That provided fix was just pushed to git (see third e-mail in the
thread:
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-June/212766.html
)

git pull should fix your issue.
