Hi @bpfoley . Thanks for your contribution! I have merged it to our llvm6 branch, and I will merge to master after my testing.

Do you have similar issue?

Yes, I'm seeing the same issue. :(

The issue can be solved by compiling LLVM by yourself instead of using the binary downloaded from LLVM's website.
