Showing gdb with debuginfo loaded doesn't show more in the backtrace.
It does show:
Cannot access memory at address 0x44c70808

process started with "sh cam01-launch" where cam01-launch contains:
gst-launch gstrtpbin name=rtpbin rtspsrc location=rtsp://192.168.1.70:7070 !
tee name=t t. ! queue ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink
host=192.168.1.1 port=37886 rtpbin.send_rtcp_src_0 ! udpsink host=192.168.1.1
port=37887 sync=false async=false t. ! queue ! decodebin ! videorate !
video/x-raw-yuv,framerate=1/60 ! ffmpegcolorspace ! pngenc snapshot=false !
multifilesink location="/home/dave/cam01.png" t. ! queue ! rtpmp4vdepay !
filesink location=/home/dave/cam01.mp4

The process (in this case) ran for about 14 hours and 40 minutes before the
segfault.
The process did not terminate, but the stream stopped recording to the disk,
the snapshots stopped,
but the stream from the camera continued until the process was killed.

This has happened several times with the amount of time that the process runs
varying from about 40 minutes up to the 14 hours+.

I'll start it again with gst-debug-level set to 3 and send the output later.
