Please show a recipe for reproducing this problem with a recent Git
version and preferably with the latest pretest of Emacs 25.1.  Please
include any files necessary for the reproduction.  Before we dive into
this tricky issue, I'd like to be sure the problem still exists (since
more than a year has passed since your original reports).

Also, this is specific to MS-Windows, right?

Thanks.
