--- Comment #3 from Reid Kleckner <rnk at google.com> ---
Fixed in r196402.
Sebastian Redl pointed out that I need to fix C++11 list construction:
$ cat t.cpp
extern "C" int printf(const char *, ...);
struct A { A(int, int) {} };
int f(int i) {
printf("%d\n", i);
return i;
}
int main() {
A a{f(1), f(2)};
}
This now prints 2, 1 with clang. MSVC 2013 CTP actually has the same behavior,
so they are non-compliant. I think for the moment we have to be bugwards
compatible. If they change, we can key our behavior off of -fmsc-version.
