x86 (32-bit) build of 1.18.0, 1.19.0, 1.20.0, svn snapshot seems to incorrectly decode the attached mp3 snippet. At the point where the right channel is expected to clip (typical), the output waveform seems to jump back to 0(?) instead, and it sounds like static. configure --with-cpu=i486. Noticed originally with 1.18.0-1 in Debian sid. On my amd64 machines, and with other decoders (exculding mplayer), everything is fine.
