1. code below compiles into many instructions like "movl $0, 16(%eax)", should
have been "stosw" since all initializations are zeros. Even if one or two are
skipped in the middle still bulk stosw should be used.
2. Even when class E with external constructor uncommented this shouldn't change
since constructor can't change any data in C.

class E {
// int j;
public: E();
};
class C {
int h, i, j, k, l;
// E e;
int m, n, o, p, q, r, s, t, u, v;
public:
C();
};
C::C() : h(0), i(0), j(), k(0), l(0), m(0), n(0), o(0), p(0), q(0), r(0), s(0),
t(0), u(0), v(0) { }
