Yes. See the errata for the manual at

If you set ioutfm=1 and ntxo=2, then you will never see the problem that
coordinates overflow fixed-size fields and replaces the coordinates with
***s. It's possible to run long enough that the single-precision
trajectory files may lose precision for the particles that have migrated
very far away from the original box, though (although you probably have
to run for a very long time for this to become a real problem).
