I realize we are reading from garbage. In this case whether we interpret the garbage as true or false doesn't really matter (in terms of doing something potentially bad in either case). I'm just wondering if the act of accessing the memory (which causes a bus error on the emulator), will leave our app or the OS in a bad state....

Doesn't this amount to reading a value from an ill-defined location then taking an action based on the value? Sounds like trouble brewing...
