Exactly. And honestly, I'm not sure if it makes sense to enable 
"-Wnull-dereference" with asserts disabled. You enable half of the 
checks and compain about the other half generating more warnings than 
before. The variable can still not get NULL at runtime or the assertion 
would have been thrown when enabled (which it doesn't, of course :)
