Subcategory: korn93
Type: Defect

Status: 7-Fix in Progress
Substatus:
Priority: 2-High

=== *Description* ============================================================
I have a script that starts a sub-shell. When I suspend the subshell, to return
to the login shell, often the login shell logs out. Sometimes the login shell
hangs with a message saying I have stopped jobs, and then I can't type into the
window. (In both cases I'm using rlogin or ssh to login.)
/bin/ksh doesn't have this problem.
If I use /bin/ksh for the login shell, and /bin/ksh93 for the sub-shell, the
problem doesn't occur.
This seems like another job control / tty modes race condition.
*** (#1 of 2): 2008-03-06 21:53:18 GMT+00:00 <User 1-5Q-7624>
After some experimentation, I found the key to reproducing the problem:
$ kk() { "$@"; }
$ echo $SHELL
/bin/ksh93
$ kk $SHELL
$ kill -STOP $$
After executing the above, you'll be back in the parent shell.
Hit CR and the parent shell will die.
