        * resolve.c (resolve_assoc_var): If the target expression is a
        deferred charlen dummy and the associate name shares the
        charlen, generate a new one. Make sure that new charlens are in
        the namespace list so that they get cleaned up.
        * trans-array.c (gfc_is_reallocatable_lhs): Associate names are
        not reallocatable.
        * trans-decl.c (gfc_get_symbol_decl): Put deferred character
        length dummy and result arrays on the deferred initialization
        list so that the variable length arrays can be correctly dealt
        with.
        * trans-expr.c (gfc_conv_string_length): Return if 'expr' is
        NULL rather than ICEing.
