This program writes one word and then reads two words. g77 finds the error but
gfortran does not -

[dranta:~/tests/gfortran-D] dir% gfortran -o read01 read01.f
[dranta:~/tests/gfortran-D] dir% read01
[dranta:~/tests/gfortran-D] dir% cat read01.f
      program test
      integer i1,i2
      open(unit=11,form='unformatted')
      write(11)i1      
      close(11,status='keep')

       open(unit=11,form='unformatted')
       rewind 11
       read(11)i1,i2
       close(11,status='delete')
       stop
       end[dranta:~/tests/gfortran-D] dir% gfortran --v
