             Bug #: 57141
           Summary: Cannot change attributes of USE-associated intrinsic
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: roger.ferrer@bsc.es


Hi,

gfortran-4.8 (and 4.7 as well and possibly earlier versions too) complain with
this snippet.

The error message is not emitted if the declaration of R is uncommented.

! -- test.f90
MODULE M
    INTRINSIC :: NULL
    !! Uncommenting the following statement
    !! causes the error go away
    ! REAL, POINTER :: R(:) => NULL()
END MODULE M

MODULE M_INTERN
    USE M
    IMPLICIT NONE
    REAL, POINTER :: ARR(:) => NULL()
END MODULE M_INTERN
! -- end of test.f90

$ gfortran -c test.f90
test.f90:12.37:

    REAL, POINTER :: ARR(:) => NULL()
                                     1
Error: Cannot change attributes of USE-associated symbol null at (1)

Kind regards,
