[cfe-dev] [StaticAnalyzer] I think ExplodedGraph is wrong

Hello!

When I analyze this code:

    extern int Min,Max;
    
    void dfsd(int b) {
        if (!(b >= Min && b < Max))
          return;
        b++;
    }

It says that "b++;" is unreachable. When I look at the ExplodedGraph it seems to me that there is no node below the return. I would like to debug this. But I don't know where I should look. Do you have some idea?

Best regards,
Daniel Marjamäki
