This indicates that you need to run a full rebase 
(https://www.cygwin.com/faq.html#faq.using.fixing-fork-failures).  The 
simplest way to do this is to run '/usr/bin/rebase-trigger full', then 
stop all Cygwin processes and services, and then run setup-x86.exe.  The 
_autorebase postinstall script will then take care of the rebase.

I have occasionally found it necessary to reboot the computer before 
doing this.
