If it helps here is a failed build from our bots:
https://lab.llvm.org/buildbot/#/builders/179/builds/4420

There are others but just combinations of the same tests.

Example error from the hexxagon build:

  /home/tcwg-buildbot/worker/clang-armv8-lld-2stage/test/test-suite/MultiSource/Applications/hexxagon/hexxagonboard.cpp:254:10: error: reference to 'empty' is ambiguous
                  return empty;
                         ^
  /home/tcwg-buildbot/worker/clang-armv8-lld-2stage/test/test-suite/MultiSource/Applications/hexxagon/hexxagonboard.h:42:2: note: candidate found by name lookup is 'empty'
          empty,
          ^
