This one _might_ not be a scipy problem. I don't have time to track it right
now, but google for Andrew Straw in the numarray list for some recent messages
regarding floating point exceptions. He was running into similar issues, and
it turned out to be a very obscure glibc bug. You might want to look into
that before spending too much more time on it from the python side, since it
was quite tricky to track down, and _not_ the kind of thing you'd think of first.
