Rob, the area where the parameters are passed still contains old parameters from previous calls. If a parameter wasn't passed, there may or may not be an old pointer at the spot where the program would be looking for the parameter. Just checking %addr might get a false positive, and the program would access some storage, who knows where. Just using the value would cause the procedure to run incorrectly; changing the value would cause storage corruption somewhere, which may or may not cause really really bad things to happen.
