--- Comment #7 from janus at gcc dot gnu.org ---
I think it is indeed expected for valgrind to report leaks for the code in
comment 5, since variables in the main program are not supposed to be
auto-deallocated in F08.

Valgrind does not show any leaks if I put x into a subroutine:

  type :: thytype
    integer(4), allocatable :: h(:)
  end type thytype
  type :: mytype
    type(thytype), allocatable :: q(:)
  end type mytype
contains
  subroutine s
    type (mytype) :: x
    x = mytype ([thytype([555])])
  end subroutine
end

One should check the test cases listed in comment 0, in order to see if they
still show leaks and if those are actual bugs.
