Bug with local variable

[Mario Jungwirth]

Hello

I found a bug with local variable. 
My source (The directory dosn't exists!!!)

function test()
{
    local myreturn=$(ls -la /directoryNotExists)
    echo "return value=$?"
}

The "return value" is now 0!
If i remove the "local" the "return value" is 2 <-- this is correct.

Is this a bug or do I something wrong?
