[Bug fortran/45290] New: [F08] pointer initialization

["janus at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

John Reid, The new features of Fortran 2008, chapter 5.5:

A pointer may be initially associated with a target:

type (entry), target :: bottom
type (entry), pointer :: top => bottom

*****

Currently gfortran responds with:

type (entry), pointer :: top => bottom
                               1
Error: Pointer initialization requires a NULL() at (1)

*****

A look at the current draft of F08 seems to indicate that this is allowed for
any kind of pointer: Data pointers and data pointer components as well as
procedure pointers and procedure pointer components. See:

R442 component-initialization
R443 initial-data-target
C460

R505 initialization
C511

R1216 proc-pointer-init
R1217 initial-proc-target

Note: For procedure-pointer components I was not able to find any specific
reference to non-NULL default initialization. However, chapter 4.5.4.6
("Default initialization for components") explicitly mentions the possibility
of having an initial-proc-target for a PPC.
