    Fortran: avoid NULL pointer dereferences

    CLASS(), PARAMETER is not yet properly implemented in gfortran.  Using =
it
    in declarations could lead to subsequent NULL pointer dereferences duri=
ng
    checking or simplification of expressions involving those CLASS variabl=
es.

    gcc/fortran/ChangeLog:

            PR fortran/103137
            PR fortran/103138
            * check.c (gfc_check_shape): Avoid NULL pointer dereference on
            missing ref.
            * simplify.c (gfc_simplify_cshift): Avoid NULL pointer derefere=
nce
            when shape not set.
            (gfc_simplify_transpose): Likewise.
