Description cyrilbur 2022-02-08 15:48:37 UTC 
Setting -echo and leaving a dangling fork results in an ash crash.

I have a relatively stripped down busybox, I am using the busybox coreutls.

Reproduce:

stty -echo
sleep 1 & ps &
             ^ This is the problem

ash will crash.

I have done the same thing with bash and dash and neither crash.

If I have time I will endeavour to get more information.

Can't reproduce: does not crash for me.
Tried on current git: v1.36.0.git
