4 | Subject: [PATCH] Define _DBUS_ALIGNOF using _Alignof when using C11 or newer | ||
5 | |||
6 | WG14 N2350 made very clear that it is an UB having type definitions | ||
7 | within "offsetof" [1]. This patch changes the implementation of macro | ||
8 | _DBUS_ALIGNOF to builtin "_Alignof" to avoid undefined behavior. | ||
9 | |||
10 | clang 16+ has started to diagnose this [2] | ||
11 | |||
12 | Fixes build when using -std >= gnu11 and using clang16+ | ||
