I just ran into trouble in a simple md run while
using 3Dnow! on an Athlon processor.
The energies suddenly became excessively high (>1E+20).
This just happens from time to time. Disabling the assembly
loops everything runs smoothly. This does not happen
when using SSE on AthlonMP.
The error happened on a FreeBSD-4.5 box.
I remember something about errors in the assembly loops
some (longer) time ago.
