Note, this is not a current issue in Cygwin= , but is believed to become a FUTURE issue with the next release. It looks like you've bumped into the bug reported here: https://cygwin.com/ml/cygwin/2019-07/msg00152.html This was a bug in a development snapshot, and it has already been fixed. Y= ou=20 should try the test release for cygwin-3.1.0 to confirm this. I don't think this problem has anything to do with commit=20 b0c033bf3fae810b9e5a5c69f17bd4de63725691.
