even if I use a magnetic needle to change the bits in my RAM ? :)

There's an easy answer to that: using a magnetic needle to change the bits in your RAM violated the assumptions of the compiler, leading to undefined behaviour. What exactly will happen in that circumstance is just that: undefined.

To put that another way: hardware failures are beyond the scope of the compiler.

Maybe your compiler.
