Thread-topic: Changed behavior of jacobisvd

I'm not sure if this is a sign of anything wrong, but I noticed the following change in updating from eigen 3.2.1 to 3.2.4 using Visual Studio 2013.

For the matrix:

1 2 3
0 0 0
7 8 9

JacobiSVD used to give 0 as the minimum singular value. Now it is 1.4079439049813084e-033

MATLAB and Wolfram Alpha give 0.
