Hi Tim, I don't know if you noticed the thread starting here: https://cygwin.com/ml/cygwin/2019-12/msg00016.html The problem reported there has been fixed, and I hope that the fix also works for your problem. You can test it by installing the latest snapshot from https://cygwin.com/snapshots/. Thanks.
