Bug#805109: libavresample2: Segfaults when trying to play certain song

[Helge Kreutzmann]

Package: libavresample2
Version: 6:11.4-1~deb8u1
Severity: normal

I use cmus a lot and it has never crashed. However, now I can
reproducibly crash cmus with a SegFault.

I rebuild cmus and libavresample2 with "nostrip" and ran cmus in gdb.
When issuing "bt full" I get the following:

Local build mplayer plays the file just fine.
