>From https://bugs.llvm.org//show_bug.cgi?id=33065#c5 it seems that this is indeed a sequence bug in the previous version of this code and not a compiler bug. 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.
