Casting an array form an associative array

[Jacob Carlborg]

The following example:

void main()
{
    void[][size_t] aa;
    aa[1] = [1, 2, 3];
    if (auto a = 1 in aa)
    {
        writeln(*(cast(int[]*) a));
        writeln(cast(int[]) *a);
    }
}

Will print:

[1, 2, 3, 201359280, 0, 0, 0, 0, 0, 0, 0, 0]
[1, 2, 3]

The first value seems to contain some kind of garbage. Why don't these 
two cases result in the same value?
