It needs more testing because at least three other developers believe 
that you're not fixing a bug, you're masking another bug.

You need to prove to us that the bad pointer is not being passed in 
because of another wine bug, and that Windows really does check for bad 
pointers using IsBadWritePtr.

Sorry, to be a pain, but Wine development is hard...
