So should this considered a bug then and be filed?

I think so. I have a related EnhancementRequest open, but I have to
close it down or modify it...

int mightUpdate(int& x)
{
    ...
    return x;
}

{
    ...
    a[mightUpdate(i)] = mightUpdate(i);
    ...
}

Is this also a bug?  How would the compiler know whether to emit a 
diagnostic for this case?
