Thanks Mark! Now we don't have the LLVM error as before.

However, I think this time we are hitting something in emscripten. The same
gist is updated: https://gist.github.com/xxuejie/8384185. This time we are
getting an error in JSBackend. So Alon, can you help take a look at this?

Thanks all of you for your help!

Best Regards,
