Hello, I noticed the committed patch "gameux: Add implementation of IGameStatisticsMgr::RemoveGameStatistics." (5cac9d2cb2c020802a56a5b1b28348316f1087ba) The GAMEUX_getAppIdFromGDFPath() function now ends with: + HeapFree(GetProcessHeap(), 0, lpRegistryPath); + + TRACE("found app id: %s, return: %#x\n", debugstr_w(lpApplicationId), hr); + return hr; In most of the error paths, lpRegistryPath is not initialized, so it's pointing to garbage; I think just initializing to NULL should be sufficient; Similarly, in that case, lpApplicationId is not initialized, so it contains garbage; Tracing will probably print some random stack bytes before hitting a zero byte. I'm not completely sure what should be done about this issue; I think it should probably only be traced on success, perhaps tracing the error otherwise; Any ideas? HTH, Joris
