The example does not look like valid Fortran, so I'm not too bothered
if fortran-mode cannot indent it (although an infinite loop is not a
nice way to fail).
Do you have a minimum example of a valid Fortran file that fails in
this way?
The problem is another (see eg bug #2106) infinite loop in
end-of-defun, when called from the start of the "20" line. It's not
immediately obvious to me whether this is a problem in fortran-mode or
in end-of-defun.
