Hi Eric,

sorry for breaking this. I still don't fully understand what do you mean by out-of-tree builds here. Can you please provide more specific instructions on how to reproduce the issue?

As for the change, while it might fix compilation issues, it does not address the fact that compiling Clang under UBSan without the blacklist will raise UBSan reports due to known a undefined behavior in libstdc++ in stl_tree. So, I would really like to understand the conditions under which it fails.
