This sample is just too short. Make it at least 4x as long (just open it
in Audacity, copy the content, paste it at the end of the original
sample three times and export the whole as FLAC) and you will be able to
reproduce the bug. Otherwise I'll upload the file (26MB). I just didn't
have anything shorter then 5 minutes to test with, so I hit the bug
immediately.

As stated in
<http://lists.mplayerhq.hu/pipermail/mplayer-users/2012-November/085621.html>,
reverting the checkin from r35333 fixes the issue with long FLAC files.

Thanks,
