Comment (by gk):
Arthur looked at it recently a bit (in #21711):
{{{
I tried to build tor-browser.git using -fsanitize=cfi and I ran into the
following bug that was reported recently:
http://lists.llvm.org/pipermail/llvm-dev/2017-February/109861.html
Fortunately, it seems this bug has been fixed in clang 4.0. Binaries for
clang 4.0.0 should be available in a few days so I will try again then.
See https://clang.llvm.org/docs/ControlFlowIntegrity.html
