Comment (by sukhbir):
So I tried building with clang 6 today just to confirm the theory that one
of these bugs was fixed in clang 6.0.0 (and hope the other one was as well
:) and ran into the following error. I replaced the precompiled clang
webrtc with clang 6.0.0 but I didn't bother to set `clang_base_path` and
just replaced it in the default lookup directory `third_party/llvm-
build/Release+Asserts`.
I will continue to debug this (and try with master instead of release as
well) but if you have seen this before, please let me know. A quick search
tells me this may be related to cross-compilation but I haven't found any
solutions yet.
