Question: [I asked a question](https://stackoverflow.com/questions/35136918/objective-c-fabsf-wrong-result-type) some time ago now. I was trying to understand what I was not understanding of an interface, and in the comments came out it was (likely) a bug in the interface itself.

I opened a ticket in their (Apple in this case) bug tracker, and after a year the ticket is still not even considered. 

It was a minor issue, but I wonder:

*What is best to do with the question: should I leave it unanswered, or shortly answer myself "it's likely a framework bug or whatever"?*

Answer: 
I think it would be okay to add a self answer stating that the issue in the question appears to be a bug and then link to the bug report so future visitors can see it. This way people who hit this same issue at least see that there is a problem, it is just not solved as it is a bug. I really dislike having that as just a comment as comment as for clarification and confirming it is a bug is more an answer to me.

Once/if it is ever fixed the answer can be updated to include the fix information.
I have deleted my own question because it not only became useless for me, it was a bug, was properly fixed by the maker *and* was getting in the way of people looking for information about the error but that didn't have the same causes. So, yeah, if you find that your question is no longer useful, you can delete it.
