Bug when building tests on sandy bridge

Hi,

I tested GCC 4.5.3 and it also fails. I'm sure you will have that issue also 
when you use Vc in your program, not only in the unit tests. That's why I 
created an issue to be fixed before 6.0:

I guess what happens is that GCC generates incorrect asm for one or more 
intrinsics. Let's see whether it can be worked around.

Cheers,
	Matthias
