Compiling valid C++11 code causes clang++ to segfault during struct generaion.

Repro Steps:
Download the attached .sh and .cpp files onto an x86_64 Ubuntu 16.04 install,
with the standard apt compiler version (3.8.0-2ubuntu4
Run the attached .sh script with the attached .cpp file generated by clang++
Actual Results:
clang++ segfaults during codegen.

Expected Results:
Either a compiler error or a working binary. g++ (Ubuntu
5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609 is able to produce a working binary on
the same source clang++ segfaults on.
