Original ticket http://projects.scipy.org/numpy/ticket/627 on 2007-12-09 by trac user Czarny, assigned to @cournape.

When I call the svd function with an array it takes 100% of my CPU and never actually finishes the calculation. Python needs to get killed manually (Ctrl+C doesn't work as usually).

I've tested that on:
Linux:
Linux kacper 2.6.22.10_laptop-0.6 #1 SMP PREEMPT Sun Oct 21 17:48:51 CEST 2007 i686 Intel(R)_Pentium(R)_M_processor_1.70GHz PLD Linux
python-2.5.1-4.i686
python-numpy-1.0.4-1.i686
(I've tried with earlier 1.0.3.1 as well)

Windows:
i686
python-2.5
python-numpy-1.0.4

I've used two scripts found on the net (google with 'svd python') and both behave in exactly the same way
