errexit inconsistent behaviour with pipelines

Hello, I have these three very simple scripts. The only difference between them is the penultimate line of each of them: | $ head -n 6 just_pipe just_for_loop pipe_and_for_loop | ==> just_pipe <== | set -e | trap 'echo aborted in line $LINENO' ERR | echo start | true | false | echo ended succes

is it a bug? (little script)

#!/bin/bash -e trap "rm test_fifo" 0 mkfifo test_fifo ls / > test_fifo & exec 9<&0 while read dirname do echo $dirname # if I wait, exits!!! read -t 2 -p "press enter..." 0<&9 done < test_fifo exec 9<&- exit 0
