Machine Type: x86_64-unknown-openbsd6.0
Bash Version: 4.3
Patch Level: 46
Release Status: release
Description:
When declaring a variable in a function as a nameref, it can not
be dereferenced if the variable it's a nameref to happen to have
the same name as the nameref itself. This imposes unnecessary
restrictions on the caller.
Also seen in GNU bash, version 4.3.39(1)-release (x86_64-apple-darwin15).
Repeat-By:
function bug {
typeset -n var="$1"
printf "%s\n" "$var"
}
var="hello"
bug var
Result:
bash: warning: var: circular name reference
Expected result: The string "hello" outputted with a terminating
newline (as with ksh93).
