How about this case then? 
Vector4 does not get allocated with new now. 
Why does this case not work? IMHO, Gcc should see: oh, I have something of type 
__m128, I better align __m128 to 16 when I create an instance of Foo... 
 
#include <xmmintrin.h> 
 
class Vector4 
{ 
public: 
	Vector4() { vec = _mm_setzero_ps();  } 
	 
	__m128 vec; 
}; 
 
class Foo 
{ 
public: 
	float a; 
	Vector4 foo; 
 
	Foo(const Vector4 &v) 
	{ 
		foo = v; 
	}	 
}; 
 
int main(int argc, char **argv) 
{ 
	Foo *foo = new Foo(Vector4()); 
}
