C++ source that brings clang-5 into an infinite loop wiht -O3
The attached reduced C++ code compiles with
clang++-4.0 -emit-llvm -S -O3 -std=c++14 c.ii
as well as with
clang++-5.0 -emit-llvm -S -O2 -std=c++14 c.ii
However, it appears to run indefinitely with
clang++-5.0 -emit-llvm -S -O3 -std=c++14 c.ii</pre>
