 - What I was trying to accomplish:
 I am trying to stream ALSA audio in (one channel) over RTP, to a VLC
 server with pcm_alaw/pcm_mulaw format @8ksample/s.

 - The problem I encountered:
 After few seconds (from 5 to 100, randomly) of correct and audible sound
 on server (but with wrong stream speed), the program (ffmpeg) exit with
 "segmentation fault".

 - Exact command line:
 ./ffmpeg -f alsa -ar 8000 -ac 1 -i hw:1,0 -ar 8000 -acodec pcm_alaw -ab
 64k -f rtp rtp://127.0.0.1:1234

 - Output of ffmpeg -v 9 -loglevel 99 -report:

 - Output of debug as described here [http://ffmpeg.org/bugreports.html] :
 [http://pastebin.com/zBsWAPgQ]

 - Summary of the bug:
 Program exit with segmentation fault

 - How to reproduce:

 run command and wait few seconds
