And then "ddd" is a fairly-nice GUI wrapper around debuggers (including
"gdb" (the default) and other debuggers like Intel's "idb" (which can be
set as command-line options)). See

In principle the KDE project's "kdbg" could also be used, but I have
persistently had trouble getting it to work with Fortran executables;
I'm not sure what's going on there ;-(
