            Bug ID: 23661
           Summary: [3.5] Crash when creating tuple with at least 5
                    elements using libc++
           Product: clang
           Version: 3.5

Test case

Attempting to compile the attached test case with clang++ 3.5.2 and libc++
causes the compiler to crash. Things work if I use clang++-3.4 or libstdc++
instead. To reproduce, here's the exact command I used to compile:

  clang++-3.5 -std=c++11 -stdlib=libc++ test.cpp -DCRASH

Here's the exact version number of the clang 3.5 I'm using:

  Debian clang version 3.5.2-svn232162-1~exp1 (branches/release_35) (based on
LLVM 3.5.2)

My libc++ is from revision 230077 (a bit old, I know, but <tuple> has only seen
two patches since then, and still, it shouldn't *crash* the compiler).

I'll post the backtrace in a followup comment.
