[Bug libfortran/24796] New: end-of-record error when writing

["chjacob at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

I found a problem with writing an unformatted file after
reading from it and encountering an end-of-file during
this reading. In that case it is not possible to write 
to the file anymore.

I do not know what the standard says about this, but
ifort accepts this.

christoph@note-jacob:~/chemie/sources/gfortran-bugs/write > cat write.f90

program bla
  implicit none
  integer, parameter :: iunit=30
  character(len=8) :: b

  OPEN(IUNIT,FILE="BLA",STATUS='NEW',FORM='UNFORMATTED')

  read (IUNIT, ERR=10, END=10) B
  10 continue

  write (iunit) "bla"
  CLOSE(IUNIT)
end program bla
