if (0) [super dealloc];

That never calls the method, but the checking code in the compiler is  
not clever enough to realise that, so it thinks that -dealloc has  
been called and refrains from generating the warning.

Better would be a pragma to tell the compiler to suppress the  
warning, but the person who added the warning to the compiler didn't  
provide any such mechanism to turn it off.
