`Ty && "Trying to add a type that doesn't exist?

Hello,

I’m having this error and couldn’t find a resolution from online, any help would be greatly appreciated:

Is there any clue for this error ?

Thanks

I think this is https://llvm.org/bugs/show_bug.cgi?id=16846

Yes, I found this link, but what’s the solution??

Upgrade clang? I can't reproduce it with trunk.

how do I get the trunk ?

I downloaded llvm3.6.0 from the website
