OK, here is the minimum script that demonstrates the bug:
=== script ===
#!/bin/bash
declare var="hello world"
declare -n ref
ref=var
echo $ref
ref=var
echo $ref
--- output ---
hello world
var
The equivalent "1 out of 4" script that works correctly:
#!/bin/bash
declare var="hello world"
func() {
local -n ref
ref=var
echo $ref
local -n ref # the workaround
ref=var
echo $ref
}
func
