I'm found bugs in ReactOS with wine tests http://www.reactos.org/testman/detail.php?id=2537184. If buffer size is a 0xdeadbeaf, ReactOS WideCharToMultiByte fail. Also Windows realization of WideCharToMultiByte. If Wine realization not fail, it a problem of Wine.
Please provide a test case (preferably as a part of Wine test suite) to show that's a real Wine problem and not something not related (like a bug in ReactOS).
