Small test code

I'm sure this is not a bug but a user error/config issue, but I thought I'd
report anyway.  This is against current trunk of LLVM/clang (see version number
below)

Can someone just check that this code compiles and runs without segfaulting?

Compile with 

clang++ -O0 -g -std=c++11 -fno-exceptions -fno-rtti
-I${path/to/clang/build}/lib/clang/7.0.0/include
-I${path/to/clang/build}/include main.cpp -o a.out -lLLVMSupport -lpthread
-ltinfo -lclangFrontend  -lclangSerialization -lclangDriver -lclangParse
-lclangSema -lclangAnalysis  -lclangEdit -lclangAST -lclangLex -lclangBasic
-lclangTooling -lclangToolingCore -lclangFormat  -lclangRewrite
-lclangASTMatchers

Run on any source file.

My setup:
clang version 7.0.0 (trunk 324074)
Target: x86_64-unknown-linux-gnu
Thread model: posix
clang version 7.0.0 (trunk 324074)
Target: x86_64-unknown-linux-gnu
Thread model: posix

gcc (Ubuntu 5.4.0-6ubuntu1~16.04.6) 5.4.0 20160609



Clang built with

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
-DCMAKE_INSTALL_PREFIX=${path/to/clang/build} -DLLVM_TARGETS_TO_BUILD="X86"
-DBUILD_SHARED_LIBS=true .. 

using gcc
