Summary of the bug:

I am trying to transcode a m3u8 file to mp4, this file can be played normally, I used ffmpeg-3.4.1 on CentOS release 6.8 (Final), the ffmpeg crashed; But, if I tryed it again use ffmpeg-3.4.1 on macos, it is ok.

How to reproduce:

ffmpeg -y -v info -i http://hrslive.hongrenshuo.com.cn/record/hrs/1103842484087160916.m3u8 -f mp4 -vcodec h264 -pix_fmt yuv420p -b:v 1048576 -acodec copy -profile:v baseline -g 15 -bufsize 6000k http://hrslive.hongrenshuo.com.cn/record/hrs/1096029521963909169.m3u8
