Dear Maintainer,

Upon upgrading from wheezy to jessie, liquidsoap stopped being able to stream 
mp3 to
icecast2. Streams in other formats (e.g. vorbis) continued to work. When 
running libmp3lame0
3.99.5+repack1-7, errors appeared in /var/log/messages:

May 15 11:53:28 fluffy kernel: [ 3874.762067] liquidsoap[1515] general 
protection ip:b682f0c9 sp:b28f9538 error:0 in 
libmp3lame.so.0.0.0[b6801000+48000]

I was finally able to get it working again by reverting to libmp3lame0 
v3.99.5+repack1-3.
More specifically, I:

- built a fresh wheezy system
- installed icecast2 & liquidsoap
- made a backup of /usr/lib/i386-linux-gnu/libmp3lame.so.0.0.0
(md5: 6a3c42fe4c459d1815950a32db828e41, this is from 3.99.5+repack1-3)
- pointed /etc/apt/sources.list to the jessie repository
- apt-get update
- apt-get install icecast2
- apt-get install liquidsoap
(liquidsoap continued to work at this point, until it was restarted)
- copied the backup of libmp3lame.so.0.0.0 into /usr/lib/i386-linux-gnu/
- restarted liquidsoap successfully

Taking the wheezy->jessie upgrade a step further by doing an apt-get upgrade and
apt-get dist-upgrade resulting in libmp3lame.so.0.0.0 being replaced with a 
newer version
again, which reintroduced the general protection error. Again, when I reverted 
back to
the older version of the library the issue went away.

I'll also note that I was able to reproduce the issue with a fresh jessie 
install.

I've rebuilt this system several times trying to resolve this issue. The system 
has a fairly
minimal install (only the SSH server package is selected during the install 
process, only
icecast2 and liquidsoap are installed after the build is complete). I've also 
reproduced this
on two different i386 systems, although both are AMD Athlon based.

Thanks,
