[Bug fortran/20125] New: gfortran - backspace on binary files errors

["dir at lanl dot gov" <gcc-bugzilla at gcc dot gnu dot org>]

I don't know if backspace ever works, but while trying to run some calculations
the read after a backspace got some run time errors, crashed, and sometimes hung
the program -

[dir:~/tests/gfortran] dir% gfortran -o backspace backspace.f
[dir:~/tests/gfortran] dir% backspace
At line 5 of file backspace.f
Fortran runtime error: End of file
[dir:~/tests/gfortran] dir% cat backspace.f
      program main
      i=1
      write(3)i
      backspace 3
      read(3)i
      stop
      end
