Patch Level: 17
Release Status: release
Description:
The `declare -n variable` call seems to have inconsistent behavior.
Use the Repeat-By code to see a clear example.

Example code:
```bash
declare -n z
echo "${z}" # "" (empty)
z="somevalue"
echo "${z}" # "" (empty)
declare -n z
echo "${z}" # "" (empty)
z="somevalue"
echo "${z}" # "somevalue"
```
