 gdb has problems with printing info about allocatable arrays. Allocatable arrays have to be displayed as "*((real_8 *)my_array + N)@M" where N is number of elements beyond first element and M is number of elements to show. (See bottom of this page (and links therein) http://stackoverflow.com/questions/11786958/how-to-print-fortran-arrays-in-gdb)
+It is sometimes useful to let the compiler tell you about additional errors. Assuming you use gfortran on your PC: See https://gcc.gnu.org/onlinedocs/gfortran/Code-Gen-Options.html for additional options. For example if you want to check just about everything, add "-fcheck=all" to the "FC_FLAGS" in the gfortran section. (Note: Running configure again re-generates the Makefile)
