to do a proper analysis, you can get a one week trial license for Linux from PVS, see http://www.viva64.com/en/b/0441/ . A quick usage example for deal.II is in this issue. In that thread there is also a script to create Github issue for each analysis, if you would like to cover them and track progress.
