Description
In this thread http://ffmpeg.test-lab.ch/viewtopic.php?f=12&t=20#p47 i am describing the steps of Segmentation Fault.
Below is the output with gdb ffmpeg_g:

Sorry for the incomplete report. So here i think is all that you need.
Steps to reproduce it:
1) RTP streaming of a YUV420p file:
ffmpeg -re -s 352x288 -f rawvideo -pix_fmt yuv420p -r 10 -i sample_352x288@10_YUV420p.yuv -an -vcodec libx264 -preset fast -profile baseline -threads 0 -r 10 -s 352x288 -b:v 200k -flags global_header -f rtp rtp://127.0.0.1:9999 ;
2) Create the feed for ffserver:
ffmpeg -i stream.sdp -vcodec copy http://127.0.0.1:8090/feed1.ffm
3) Start the ffserver: ffserver -d -f ffserver.conf
The ffserver.conf is :
Port 8090
BindAddress 0.0.0.0
MaxClients 10
MaxBandwidth 40000
NoDaemon

Sorry for never looking into this, it seems FFserver lacks an active maintainer;-(
I believe the crash was fixed at some point, FFserver currently ignores command line arguments, see ticket #1970 (it contains the revision that introduced above crash afaict).
