You can read that response for the properly-cited wording but my TL;DR/understanding is for the given code: struct foo bar = { .a = (c = 0), .b = c, }; That the compiler is allowed to reorder the initializations of bar.a and bar.b, so what the value of c here might not be what you expect. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
