[Bug fortran/30435] Slash at end of input not recognized according to standard

["kargl at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from kargl at gcc dot gnu dot org  2007-01-11 17:00 -------
The relevant section of the F2003 standard is 10.9.1.1.
It appears that in list-directed input that if we advance
to a newline during the read and the first item hit is a
/ when get it wrong.  Here a test program.


program t
  integer a, b, c, d

  ! This works as expected
  open(unit=10, file='tmp.dat')
  write(10,*) '1 2 3 / 4'
  rewind(10)
  a = -1; b = -1; c = -1; d = -1;
  read(10,*) a,b,c,d
  print *, a,b,c,d

  ! This works as expected
  rewind(10)
  write(10,*) '1 2 3 /'
  rewind(10)
  a = -2; b = -2; c = -2; d = -2;
  read(10,*) a,b,c,d
  print *, a,b,c,d

  ! This works as expected.
  rewind(10)
  write(10,*) '1 2'
  write(10,*) '3 /'
  rewind(10)
  a = -3; b = -3; c = -3; d = -3;
  read(10,*) a,b,c,d
  print *, a,b,c,d

  ! This fails as reported.
  rewind(10)
  write(10,*) '1 2 3'
  write(10,*) '/'
  rewind(10)
  a = -4; b = -4; c = -4; d = -4;
  read(10,*) a,b,c,d
  print *, a,b,c,d

  close(unit=10, status='delete')
end program t
