The most basic example would be two threads trying to write the same variable concurrently without synchronisation. As far as I know, as long as you don't use any unsafe code block, it is not possible, i.e. the compiler will protest loudly and the program won't compile.
You are forced by the compiler to implement an explicit exclusion mechanism.
The point is that kind of issue are silent bugs most of the time(up to point) in C, C++. It can work in most cases, and one day, something goes awfully wrong because the thread scheduling is slightly different than usual.
