I believe this is a classic case where rebasing is required.  See 
https://stackoverflow.com/questions/33125842/what-does-rebaseall-in-cygwin-do 
for details.  Sometimes the problem can be fixed by rebooting and 
starting a Cygwin app (e.g., Bash) very soon after boot (so that the 
DLLs get loaded at their preferred addressed), but that is a temporary 
workaround.

You can rebase all the DLLs as follows:

- Terminate _all_ Cygwin apps (don't forget about daemons like sshd).
- Open a Command Prompt.
- Run "ash" (a shell included with Cygwin).  Do not run "bash".
- Enter command "rebaseall".
- I usually follow this with a reboot, but that may not be necessary.

Hope this helps.
