Thanks for reporting this @DavidSpickett !

Yes, it looks like it's related, but it's not immediately obvious how exactly! I've tried testing this patch with LLVM's test-suite, but CMake does not support LLVM Flang yet: https://lists.llvm.org/pipermail/flang-dev/2021-June/000745.html. I've asked around and AFAIK, no one yet has been able to use LLVM Flang with the test-suite. So I'm not sure how people managed to set-up that BuildBot worker to work :)

There is another one here: https://lab.llvm.org/buildbot/#/builders/179. Oddly, it doesn't complain. Also, @rovka  kindly tested this patch using that worker's config before it was merged.

So, any clue what the difference between the two workers is?
