Hi @ABraun and @mdelgado, thank you…
I was able to solve the problem by reinstalling OS, going from opensuse Tumbleweed to Leap 15, and now I do not have core dumped in mt_prep_snap … just reinstalling StaMPS did not work.
I have another problem, SNAP download the srtm file “http://srtm.csi.cgiar.org/SRT-ZIP/SRTM_V41/SRTM_Data_GeoTiff/srtm_23_17.zip” … but the page is not found …
