It is a 32bit i?86 machine and my impression is that this is bug 323. The
problem disappears when ndist is stored in a "volatile double".
I have not been able to produce a test case. As there seems to be a dependency
on optimization, I am probably just unlucky. I must say that I do not
understand why bug 323 should not be regarded as a bug.
