llvm dev - Aug 2014 - [LLVMdev] Clang 3.4 yields lambda rvalue reference error while gcc doesn't

I noticed that the following program compiled with clang 3.4 yields an
error: http://coliru.stacked-crooked.com/a/844643c70280f89b

Conversely gcc doesn't (http://ideone.com/k7y55p)

If the program gets compiled in clang without the '-stdlib=libc++'
option
it compiles just fine so I suppose it might be a problem in libc++.

A quick search on LLVM's bugzilla for libc++ and lambda doesn't show any
outstanding issue. Is this a bug or am I missing something?

Thanks!
