Package: mksh
Version: 56c-1
Severity: normal
Tags: upstream
I have created a minimal script called "script" to show the problem.
To run this "script" from different shells I have created a small script called
"run-script".
I expected, that mksh would print the lines "sub_shell_exit" and "shell_exit",
but only "shell_exit" was printed.
A fix is important for me, to be able to support mksh in
https://salsa.debian.org/bs/shellia.
Please confirm, that this is a bug and not the expected behaviour of mksh.
bs@sid:/tmp/bugreport$ cat script
fkt()
{
trap -- "echo $1 >&2" EXIT
}
fkt shell_exit
$(fkt sub_shell_exit)
bs@sid:/tmp/bugreport$ cat run-script
#!/bin/sh
for sh in bash dash "busybox sh" mksh posh yash zsh; do
set -x
$sh ./script
{ set +x; } 2>/dev/null
echo
done
bs@sid:/tmp/bugreport$ ./run-script
+ bash ./script
sub_shell_exit
shell_exit
+ dash ./script
sub_shell_exit

+ busybox sh ./script
