Thanks for telling us, however I think this is just an unusual test situation not a bot error.
In https://lab.llvm.org/buildbot/#/builders/171/builds/118 Joel E. Denny fixed the test so your guess is correct. Looking at the fix https://reviews.llvm.org/rGcc60fa2685bdbff889df826a1bfd5e52ffd163c8, .lit_test_times.txt is now being removed. So when the first change ran, we generated that file then on subsequent runs we did not regenerate the file. Which caused it to fail on the builds immediately after the one with the change. Where the old file was being used instead. This would apply to any bot, which is why you saw the same thing in many places. You could argue that we should clean test folders to prevent this but you can also argue that doing so just pushes the failure onto local developers who will not be cleaning their build folders every time they do check-all. Thanks, David Spickett.
