Problem mentioned by me some time ago, may be related to this, from undocumented mandb handling of Windows localization catalog folders: https://cygwin.com/pipermail/cygwin/2018-January/235776.html which may include moving "stray cats" (also undocumented) to / [Cygwin] root so they get noticed and handled? -- Take care.
