Hmm. Not really sure how to triage this one. I filed a bug report upstream: https://github.com/inspircd/inspircd/issues/2070 In the meantime, I don't currently have a clang-based build environment; is there a way to get access to an environment where I can reproduce this issue?

I provided our project with a fixing attempt at https://github.com/inspircd/inspircd/pull/2071 Ultimatively, clang++ does not handle -v like g++ does. It's safer to use the long option --verbose.
I believe this is solved in 4.1.0.
