Are you sure? Don't you mean:    
+    if (IsEqualGUID(&IID_IDirectInputDevice8A,riid)) {   
                                            ^   
Else, it would be exactly the same as the previous check (and Wine crashes the 
same with your patch applied unaltered)...? But with the line changed as 
pointed out above, it leads to a crash in libc.so.6:
