Description of problem:

Here is simple bash script which used to work in pre 4.3 era:
(Noticed from failing lvm2 test suite)

--

#!/bin/bash

pass_() {
	declare -a var=("${!1}")
	echo "Size ${#var[*]}"
	printf "%s\n" "${var[@]}"
}

var=( "a" )
pass_ "var[@]"

--
Output with 4.3:
Size 0

--
Output with bash-4.2.45-6.fc21.x86_64
Size 1
a
--

Obvious workaround is to use different name with 'declare -a var'
but looks like serious regression in variable name processing in bash
