[Bug c++/20142] [3.3/3.4/4.0 regression] implicit assignment operator with multi-dimensional array is broken

Here's an even shorter testcase. It should return 0, but doesn't since
GCC 3.3. If I remove A's constructor, we get the failure since GCC 3.0.

======================================================
int n=4;

struct A
{
    A() {}
    A& operator= (const A&) { --n; return *this; }
};

struct B
{
    A x[2][2];
};

int main()
{
    B b;
    b = b;
    return n;
}
======================================================
