This looks more serious. 100 times machine precision is quite a large
margin in these matters. Could you perhaps stick in a printout of the
two terms and their difference?

I have an ATLAS build on AMD64 and it passes all the checks, but it is
using ATLAS 3.7.8, so you might want to try an upgrade.
