Hi Justin, I finally managed to track down this issue. Full repro is attached,
but the summary is that I'm seeing:

warning: profile data may be out of date: of 3 functions, 1 has no data and 0
have mismatched data that will be ignored [-Wprofile-instr-out-of-date]
1 warning generated.


generated from this program:

struct Foo {                                                                    
  Foo() {}
};

Foo f;

int main() {
}

It seems to have to do with the static constructor.
