Bash Version: 4.4
Patch Level: 12
Release Status: release

Description:
        Since 4.3 including 4.4 bash shows a bug in loops using nested ((...)), 
$((..)), and $(...)

Repeat-By:
The bash code

        V_NAME=Friday
        for (( INDEX=0; INDEX<$((10-$(expr length $V_NAME))); INDEX++ ))
        do
            echo $INDEX
        done

leads to

        bash: syntax error near unexpected token `newline'

whereas using backticks simply works

        V_NAME=Friday
        for (( INDEX=0; INDEX<$((10-`expr length $V_NAME`)); INDEX++ ))
        do
            echo $INDEX
        done

and yes

        V_NAME=Friday
        for (( INDEX=0; INDEX<$((10-${#V_NAME})) ; INDEX++ ))
        do
            echo $INDEX
        done

does also work, nevertheless using $(...) in the very first example is allowed
