[Bug fortran/20224] New: gfortran - flags error on strange, but correct f77 program

[dir at lanl dot gov]

I have a few old programs that do this - it is legal in f77 and actually has a
special name that I cannot recall at the moment. Absoft likes and runs it 
correctly.

[dir:~/tests/gfortran] dir% f77 -o jump jump.f

[dir:~/tests/gfortran] dir% jump

                   2

[dir:~/tests/gfortran] dir% cat jump.f
      program main
      do 20 i=1,2
      go to 30
  10  continue
  20  continue
      stop
  30  continue
      write(*,*) 'hi'
      goto 10
      end
