Say - isn't that a joke about farts of armchair crouchers.
All it says is that if you dereference garbage you get a crash.
If you're concerned, use volatile, and go shoot the compiler
programmer if she dares to optimize just anything.
And on ARM, isn't the interrupt table at ((void*)(char[])0x0)??
La vie est une rose beside that.
And all i need is atomic_compare_and_swap().
