Memory leak introduced in C++ AMP

I installed Visual Studio 2012 Update 2. I don't know if the "Update 2" introduced a memory leak, or if I hadn't noticed it before.

The code I use to test it is:

	while (true)
	{
		extent<1> e(10);
		parallel_for_each(e, [=](index<1> idx) restrict(amp) { });
	}

For every iteration, the memory consumed by the application increases around ~20kB.

Is this an actual memory leak? Is there any fix?
