Defining a class method which returns a copy of one of its members, and this 
member is declared "packed", and this member is from another class type, causes 
an internal compiler error when this method is called.

The bug was verified on both gcc 3.4.2 and 3.4.3, on i686-linux and powerpc-
linux.

The following simple program will crash g++ when compiled with -DSHOW_ICE.

---------------------------------------------------------------------------

class A
{
public:
    int i;

    A() {}
    A(const A& a) { i = a.i; }
};

class B
{
#ifdef SHOW_ICE
    A a __attribute__((packed));
#else
    A a;
#endif

public:
    B() {}
    A GetA() { return a; }
};

int main()
{
    B b;
    return b.GetA().i;
}
