C++ compiler flag vs. Yoda Conditions

In C++ programming, adding a compiler flag or pragma statement assignment within conditional expression as an error

#pragma warning(error:4706)

sorts out all programming mistakes such as this.

if (a = b) ...

On the other hand, Wikipedia says Yoda Conditions also prevents from access violation problem, but it looks like that there is no reproducable case in C++.

Thus, are Yoda Conditions of no need if we turn on that compiler option?
