Regression: Viewing avisynth files in ffplay is extremely laggy (A/V desync)

I have been using ffplay to preview Avisynth scripts before and it has worked reasonable well for a while, but I recently updated my ffmpeg executables and now the playback is extremely laggy, but only when the script has audio.
However, if I use
ffmpeg -f avisynth -i test.avs -c copy test.avi
and play the avi file, there is no lag whatsoever.
Even an extremely simple script like
exhibits this behavior.
To reproduce, install Avisynth (http://avisynth.nl/index.php/Main_Page#Official_builds, make sure you install the same arch as your ffmpeg executables) and run
ffplay -f avisynth test.avs
Like I said, any avs script has this issue, but I will attach a test file nonetheless.
