FPU problem, colinux+oM 2.4.26-1

In the email on 2/8 I said there were floating-point errors in gettimeofday.
Now I realized that this is actually a big trouble.

In a simulation program, I encounter some strange floating point error.
Simple calculation (+-*/) of floating point number give results of NaN
from time to time.

This problem was reported by ckauhaus, 
http://cluster.inf-ra.uni-jena.de/harpy/ticket/6.
But it is not a colinux bug, it is a colinux+oM bug. If one run colinux 
without oM, there
will be no problem.

The reason could be, colinux by itself  protects the FPU status 
properly. But somehow
oM will break this protection. I guess by oM itself there should be no 
such problem,
otherwise it should be found already.

So, the conclusion is, colinux+oM 2.4.26 simply doesn't work, or could 
someone
figure out how to fix the FPU status?

There is another bug that is reported, but it wasn't applied,
