["tkoenig at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Additional Comments From tkoenig at gcc dot gnu dot org  2005-09-18 19:50 -------
Not fixed in 4.0:

$ cat pointer_function.f90
program Realloc
  IMPLICIT NONE
  REAL, DIMENSION(:), POINTER :: x
  INTEGER :: i
  x => NULL()
  x => myallocate(x)
contains
  FUNCTION myallocate(p)
    REAL, DIMENSION(:), POINTER :: p, myallocate
    INTEGER :: nold,ierr
    if (associated(p)) then
       print *,"p is associated"
    else
       print *,"p is not associated"
    end if
    allocate(myallocate(20))
    if (associated(p)) then
       print *,"p is associated"
    else
       print *,"p is not associated"
    end if
  END FUNCTION myallocate
end program Realloc
$ gfortran pointer_function.f90
$ ./a.out
 p is not associated
 p is associated
$ gfortran -v
Using built-in specs.
