To which patch/post are you refering? I am not aware of such an issue.
The original patch is from Charles Davis. I attach the communication how 
I got the code. Or is here more to do?

I have an incomplete patch for that, but I've been busy lately, so I haven't had much time to work on it. (Then, of course, it needs to be turned on on x86_64/Windows, but I wasn't going to do that until I had this finished, tests in place passing, etc.)
