How 'undefined' a race condition can be?

Question

Let\'s say I define a following C++ object:

class AClass
{
public:
    AClass() : foo(0) {}
    uint32_t getFoo() { return foo; }
    void changeFoo() { foo          


        

Answer 1

Undefined behavior is guaranteed to be as undefined as the word undefined.
Technically, the observable behavior is pointless because it is simply undefined behavior, the compiler is not needed to show you any particular behavior. It may work as you think it should or not or may burn your computer, anything and everything is possible.
