[FFmpeg-user] Segmentation fault (core dumped) when run ffmpeg

[韩瑞松]

I use FFmpeg 1.2.1 to combiner a video and a audio together.
When I run the command like 
/usr/local/bin/ffmpeg -y -i '10806287.v' -i '10806287.a' -map 0:0 -map 1:0 -vcodec copy -acodec copy 10806287.mp4


output like this:
/usr/local/bin/ffmpeg -y -i '10806287.v' -i '10806287.a' -map 0:0 -map 1:0 -vcodec copy -acodec copy 10806287.mp4

Why the same command returns two different result?And How can I solve this problem.
Thank you!
