I would suspect a hardware or software problem specific to your machine.
I have a test box with a similar configuration (233MHz Pentium MMX,
RedHat 6.2), and it has no problem with the test for unreliable f.p.
exceptions. (They're reliable.)
You wrote "2.2.14". That's a pretty old kernel, which makes me wonder
if your box is 6.2 vanilla without any of the many recommended updates?
You should at least upgrade glibc and the kernel.
