I can't seem to duplicate this. This is with bash 5.2:
hobbit:~$ cat foo
#!/bin/bash
outer() {
local var3=EGG
inner
}
inner() {
local -n ref3=var3
ref3=BANANA
declare -p ref3
declare -p var3
}
outer
hobbit:~$ ./foo
declare -n ref3="var3"
declare -- var3="BANANA"
And I get the same result in older versions as well:
hobbit:~$ bash-5.1 foo
declare -n ref3="var3"
declare -- var3="BANANA"
hobbit:~$ bash-5.0 foo
declare -n ref3="var3"
declare -- var3="BANANA"
hobbit:~$ bash-4.4 foo
declare -n ref3="var3"
declare -- var3="BANANA"
hobbit:~$ bash-4.3 foo
declare -n ref3="var3"
declare -- var3="BANANA"
