Comment (by Roland Haas):

hmm, this has been fixed around
git hash ee70afd "Fixed Lorenz->Lorentz in parameter name" of GRHayL and git hash fbb3d00 "CI: fixed compilation error" of GRHayL or so, yes? Those claim be couple of days old, but maybe “commit” and “push” here are different. I’ll trigger a CI build.
