Is this segment fault raised when running `shuf`?

I have a script, where there is a line:



eval for i in "$1".."$2"; do [ ! -e "$3"/$i.* ] && echo "$i" ; done | shuf | mycommand "$3"


which means: first create a sequence of numbers, pipe them to shuf, and then pipe them to mycommand.



Most of time the script runs fine, but sometimes it gets segment fault error



/home/tim/bin/myscript: line 25: 10170 Exit 1 for i in 0001..734;
do
 [ ! -e XMJ/$i.* ] && echo "$i";
done
 10171 Done | shuf
 10172 Segmentation fault (core dumped) | mycommand XMJ


Does that mean that the segment fault is raised when running shuf?



What can we deduce from the error message and possibly correct it?



Thanks.
