<div>Doug,</div>

<div>Sorry, I missed noticing your response.</div>

<div>I'm not sure what to do here. The Clang docs (<a href="http://clang-analyzer.llvm.org/annotations.html#attr_cf_returns_retained">http://clang-analyzer.llvm.org/annotations.html#attr_cf_returns_retained</a>) note that as a Clang-specific attribute. Do you mean that we should put out a warning if some more strict standard mode is used, or that there should be a warning unless clang-specific attributes are explicitly enabled by some new option? Or should the test use some sort of "#if __has_feature(attribute_cf_returns_retained)" conditional? Or is the attribute not allowed after the function declation? Please instruct.<br>
</div>

<div>>Any chance you're also interested in tackling the related PR here?</div>
<div> </div></div>
<div>Sure. I thought it was the same issue, but I guess it's a different code path. I'm working on it.</div>
