[vlc] Crash bug in 0.8.6a+b (Win) when RTSP streaming aac

[Kim Schulz]

hi,
Just discovered a bug in vlc 0.8.6a+b for windows that makes it crash 
when streaming aac via RTSP (actually libfaad crashes and takes down vlc). 
I am streaming AAC LC 2 channel and it is setup via inline SDP
in the RTSP stream. The sdp looks like:
v=0
o=ABC 2929302000 2929307000 IN IP4 10.123.10.30
s=ABC DEMO
t=0 0
c=IN IP4 10.123.10.30
m=video 8890 RTP/AVP 96
a=rtpmap:96 H264/90000
m=audio 8888 RTP/AVP 97
a=rtpmap:97 MP4A-LATM/90000
a=fmtp:97 profile-level-id=1;cpresent=1

vlc automatically set the libfaad to use 1 channel for the audio, which
is not correct. then when I start the stream, vlc discovers this and gives
some errors. Here is the full message windows output:

at this point it crashes.
