   | bash -e -c 'echo $(exit 1) ; wait -n ; echo survived'

You really need to stop proposing nonsense when you have no idea
what is happening, or why:

        bash -ec 'true; wait -n; echo survived'

no output.   The wait -n is returning an error, there's nothing
to wait for, the '-e' test is detecting that failing.  What
came before is irrelevant.   The same in your case (try exit 0).
