I currently have a local build running to confirm the issue. That being
said, Harbormaster doesn't seem to be seeing this particular issue
(although it fails for other reasons).
I wonder if you have some some old interface files hanging around. Does this
git clean -fxd
git submodule foreach git clean -fxd
If that helps it would be nice if you could take note of which interface
files it removes so we can update the build system to clean them.
