Thanks for the explanations. I still don't know whether it's OK to have pointers to arrays with 0 elements (which are not "array objects", since "objects" are non- empty (§ 6.2.6.1.(2))). And if so, whether adding 0 to such a pointer would be valid. For the moment, it's not relevant, fortunately. > [1] https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3096.pdf Thanks for this new URL as well. I missed it. Bruno
