Slightly reduced testcase, fails at -O1 -msse2:

typedef int __v4si __attribute__ ((__vector_size__ (16)));
typedef long long __m128i __attribute__ ((__vector_size__ (16)));
__inline __m128i __attribute__((__always_inline__))
_mm_set1_epi32 (int __A) { }
extern __m128i foobar(__m128i, int);
__inline __m128i __attribute__((__always_inline__)) 
_mm_slli_epi32 (__m128i __A, int __B) { return foobar (__A, __B); }
template<typename T> class Vector {
public:
    inline Vector(__m128i x) : d(x) { }
    inline Vector(T a) : d(_mm_set1_epi32(a)) { }
    inline Vector<T> operator<<(int x) const __attribute__((always_inline));
    inline bool operator==(const Vector<T> &x) const { }
    __m128i d;
};
template<> inline Vector<int> Vector<int>::operator<<(int x) const {
    return _mm_slli_epi32(d, x);
}
template<typename T1> inline void foo(const T1 &) { }
class Fail { };
int main() {
    Vector<int> a(1);
    if ((a << 2) == (a << 2)) {
        foo(a << 2);
        throw Fail();
    }
}
