    PR fortran/95980 - ICE in get_unique_type_string, at fortran/class.c:485

    In SELECT TYPE, the argument may be an incorrectly specified unlimited
    CLASS variable.  Avoid NULL pointer dereferences for clean error
    recovery.

            * class.c (gfc_add_component_ref, gfc_build_class_symbol):
            Add checks for NULL pointer dereference.
            * primary.c (gfc_variable_attr): Likewise.
