[llvm-dev] Trunk: LLVM build is failing with a lot of `undefined reference` errors

[Evgeny Astigeevich via llvm-dev]

Hi Aleksander,

Unfortunately, I cannot help you with this. I have not used sanitizers.
Have you tried to use them despite these failures? Are they working?
I think people who develop sanitizers can help you. 
Ask their advice.

Kind regards,
Evgeny

Hello, Eugeny

Thanks for your answer.

I discovered that same regression tests are broken not only in trunk bat also in RELEASE_380/final (as you mentioned) and RELEASE_371/final.
You see, I wanted to test sanitizers from latests LLVM releases (which are unavailable out of the box on Ubuntu 14.04) on our project. It is the reason why I'm compiling LLVM from source in the first place.

Maybe you could recommend a relatively fresh LLVM release where all sanitizers are still working?
