Hard to say. As this is a Windows-only issue, I can't debug it, and there's not a lot to go on here. Unless @zmodem or @Prabhuk can help to find the root cause, the next thing I'd try is probably to reapply this without the FunctionAttrs changes -- I think that should be largely NFC (the API changes without the test changes).
