It's a quirk of YAML: `BinaryFunctionProfile` has `std::vector<InlineTreeNode> InlineTree` as optional field. Optional fields compare against the default value using `operator==`, which for vector transitively requires `operator==` for `InlineTreeNode`. However the default value for `InlineTree` is empty vector, so no `InlineTreeNode` comparison is actually necessary. Hence we just say that `InlineTreeNode::operator==` is false.
