I have been running https://cygwin.com/snapshots/x86/cygwin1-20190306.dll.xz , i.e., March 6th
For a couple hours yesterday and all day today along with Ken Brown's test version of emacs (GNU Emacs 26.1.92)
And have not had a hiccup.
(Well, to be truthful, I'm running a lot more of Ken Brown's test software than just emacs.)
