I think this is a problem with that gcc version (probably caused by the
fact that the mp3lib code does not care about C aliasing rules).
Try -afm ffmpeg, but it will be slower (you can add afm=ffmpeg, or
ac=ffmp3,ffmp2, to your config to always try these decoders first, the ','
at the end is important!).
