Other than I'd seen the one on ci.free.org recently and thought "oh, that again" and "although its been a long time", I think the failures have been rare enough that without an archive of files to search automatically, it would not be practical to find examples via just looking around via the web interface for ci.freebsd.org . I've seen rare failures in personal builds. But most of my personal builds are incremental where a old file would be around. So I expect more rare for this context. But I do not remember the ci.freebsd.org vs. personal status for the one I saw prior to the one that I reported --or when. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
