Buffer overflow in SBAS processing

[David-Loibl]

The following SBAS call ...
xdim=$(gmt grdinfo -C unwrap.grd | awk '{print $10}') ydim=$(gmt grdinfo -C unwrap.grd | awk '{print $11}') n_int=$(wc -l < intf.tab) n_scn=$(wc -l < scene.tab) sbas intf.tab scene.tab $n_int $n_scn $xdim $ydim -smooth 1.0 -wavelength 0.0554658 -incidence 30 -range 800184.946186 -rms -dem
results in this error:

mode --> 2

compute RMS misfit
compute DEM error

setting smoothing to 1.000
setting radar wavelength to 0.055 m
setting radar incidence angle to 30.000 degree
setting range to 800184.946 m
