I try to learn, how to make good Patches for wine, but sometimes, it's
difficult for me to understand:
Why not being nice and Free the allocated Memory as in my Patch?

1) Just Save some Bytes of Code
2) This is done automatic, when the Program exit's

3) We are nice, and Free all our Resources.



If we are not nice, we can also:

If we are nice, we need to insert :
