Recently Markus Metz has identified internal precision problems in
i.atcorr on certain systems which have been addressed in GRASS GIS
7.4.0RC2. Perhaps some more improvements are needed but probably also
your problem is already solved.
Please consider to update to GRASS GIS 7.4.0RC2 (the final 7.4.0 will
be out soon, your feedback would be interesting before that release).
