--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is invalid testcase.
E.g. replace return __builtin_dynamic_object_size (p, 1); with return 0;
and try both gcc -fsanitize=undefined -g -O0 or clang -fsanitize=undefined -g
-O0, both will diagnose it.
Even when C2Y allows NULL + 0, it doesn't allow NULL + sizeof (size_t).
