This is what is being discussed in the thread starting at
https://cygwin.com/ml/cygwin/2016-05/msg00327.html

Just as John I can't reproduce this.  What OS version do you run this
on, and is it 32, 32 under WOW64, or 64 bit?

Me, too, especially since we're going to have to release 2.5.2 this week.

If we don't have a solution I'll revert this patch for 2.5.2 and we can
reapply and improve it for 2.6 then.  Of course it would be nicer to
have a fix :}
