Bug#279294: SSE FP Exception

[Jason Rennie <jrennie@csail.mit.edu>]

FWIW, I'm also seeing (what I think is) this problem when I use the
atlas3-sse2 libraries instead of atlas3-base:

jrennie@karhu:~$ sudo apt-get install atlas3-sse2; sudo apt-get remove atlas3-base
[snip]
jrennie@karhu:~$ python test.py 
Floating point exception
jrennie@karhu:~$ sudo apt-get install atlas3-base; sudo apt-get remove atlas3-sse2
[snip]
jrennie@karhu:~$ python test.py 
jrennie@karhu:~$ 

I do not see this problem with atlas3-sse:

jrennie@karhu:~$ sudo apt-get install atlas3-base; sudo apt-get remove atlas3-sse2
[snip]
jrennie@karhu:~$ python test.py 
jrennie@karhu:~$ 

This was run on a Xeon (Pentium 4) machine.  test.py is attached.
