--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think the right fix is to add the && !lookup_attribute ("no_sanitize_address", DECL_ATTRIBUTES (current_function_decl)) check next to the && ASAN_STACK checks (perhaps even put (flag_sanitize & SANITIZE_ADDRESS) && ASAN_STACK && !lookup_attribute ("no_sanitize_address", DECL_ATTRIBUTES (current_function_decl)) into a special small inline predicate in that file and use it in the 4 places.
