Above appears to have been introduced in
https://git.savannah.gnu.org/cgit/bash.git/diff/jobs.c?h=devel=ee88838cf9421e2e40a7b7969cdf78a0010b075c
P.S. a similar thing happens (not resolved by reverting the above) with:
set +m; $BASH --norc -i -c 'exec xxx'
where "xxx" is not a valid command.

I printed the various declares using:
declare -p |& more
One of the early entries is:
declare -A BASH_ALIASES=()
Yet if I type 'alias |& wc, I see 56 lines starting with alias.
I _thought_ BASH_ALIASES was suppose to hold the aliases
and for an "alias whence='type -a'", I should see
Looks like the controlling process group isn't being reset correctly
after the "inner" bash exits:
$ trap 'echo "$(ps -o pid,tpgid -p $$)"' EXIT
$ echo $$
54581
$ set +m
$ $BASH --norc -i -c 'set +m; echo $$'
54583
$
exit
PID TPGID
54581 54583
When in an interactive shell with job control disabled, starting
another interactive shell, disabling job control, and then exiting,
causes the parent shell to exit after any key press.
bash-5.0$ set +m; $BASH --norc -i -c 'set +m'
bash-5.0$ [any key]
exit
This seems to work fine in bash 4.4 and
An `exec` that can't execute the supplied command seems to cause the
status of job control to become reset to the default state:
$ bash -O execfail -mc 'echo $-; exec xxx; echo $-'
hmBc
bash: line 0: exec: xxx: not found
hBc
$ set +m; echo $-
hiBHs
$ exec xxx
bash: exec:

Thank you for your reply. I am fine with the third option as far as
Hi,
thanks for a quick response. I makes sense now. Did not think about the
calls with =, my bad.

Hi,
I think bash is great and more people should use it. However, it has a bit
more picky syntax than many other modern languages and shell scripts. For
example assigning a var requires having no spaces between = and var and
assignment. I think this kind of thing can be fixed while still
