Comment (by m.dmt):
I'm also affected by this bug.
To try to narrow it down, I've encoded PCM16 wav with LAME at various
sample rates and qualities. Out of all valid MP3 sample rates only 24 kHz
is affected. If LAME encoding quality (-q) is <= 4, overread messages
appear during decoding. If quality is >= 5, these messages do not appear,
but distortions can still be heard. mpg123 decodes without audible
distortions in both cases.
