[6 Regession] Usage of unitialized pointer io/list_read.c (

[Dominique d'Humières]

With the following reduced test

program test
  implicit none
  integer :: i, j, k, ios
  integer, parameter :: big = 600
  character(kind=4,len=big) :: str1, str2

  do i=1,big, 10
    do j = 0, 9
      k = i + j
      str2(k:k) = char(65+j)
    end do
  end do
  open(15, status='scratch', encoding="utf-8")
  write(15,*) "  'abcdefgh!'", " ", str2
  rewind(15)
  read(15,*,iostat=ios) str1, str2
  close(15)
end program

valgrind shows a lot of errors before and after the commit.
