There was a problem hiding this comment.
This is "if" not "if and only if"; we're not ruing out other possible sources of undefined behavior here. (But I think it's also not possible to call a function in a way that fails to initialize a parameter of type bool -- you'd encounter undefined behavior in the caller first.)
