The following code causes current gfortran to crash with an ICE:

module linebufmod
implicit none
private

public linebuf, linebuf_add

type linebuf
  character(len=80), dimension(:), pointer :: data=>NULL()
  integer :: size=0
end type linebuf

contains

subroutine linebuf_add (buf, line)
  type(linebuf), intent(inout) :: buf
  character(len=*), intent(in) :: line

  character(len=80), dimension(:), pointer :: data2

data2=>NULL()

  if (.not. associated(buf%data)) allocate(buf%data(10))

  if (size(buf%data)==buf%size) then
    allocate (data2(2*size(buf%data)))
    data2(1:size(buf%data)) = buf%data
    deallocate (buf%data)
    buf%data => data2
  endif

  buf%size=buf%size+1
  buf%data(buf%size) = trim (line)
end subroutine linebuf_add

end module linebufmod
