[Bug fortran/44232] New: function result with pointer to strided component of argument

["Thomas dot L dot Clune at nasa dot gov" <gcc-bugzilla@gcc.gnu.org>]

(System/GCC parameters and compiler error messages given below)
Minimal Fortran reproducer:

module M_mod
  implicit none
  private

  public :: M_type
  public :: getKeys

  type M_type
    character(len=10) :: key
  end type M_type

contains

  subroutine getKeys(this)
    type (M_type), target :: this(:)
    character(len=10), pointer :: keys(:)

    keys => this(:)%key
  end subroutine getKeys

end module M_mod


Produces an internal compiler error:
