You can test it by installing the latest snapshot from > https://cygwin.com/snapshots/. Hi Ken, Many thanks for the interesting and encouraging pointer. That does look similar to my issue, though I think the other issue was (originally at least) something to do with inaccessible mounts, rather than cached mounts. I have tested the new snapshot and don't see any problems so far. However I have been having trouble reproducing my original issue, especially since I recreated my offline-files synchronisation partnership, so I can't tell for sure whether the update fixes my particular problem, or it just went away of its own accord. I'll keep exercising it and let you know if I see any more the assertion crash.
