Crash log, output, and the program's source code

Compiling the attached program with libstdc++ crashes clang++.

$ clang++ -std=c++11 tuple.cpp
$ No unexpanded parameter packs in type expansion.
$ UNREACHABLE ... 

Attached you find the diagnostic information and the short program's source (a
few lines).

Using libc++ works fine, though.

$ clang++ -std=c++11 -stdlib=libc++ -lc++abi tuple.cpp
$
