Clion 2017.3.3 syntax check is wrong but right on 2017.2.2

Yoonsung, I can't reproduce the issue on my side with the following code snippet:

#include <map>

int main() {
    
    std::multimap<int, double> traceMap;
    auto its = traceMap.equal_range(0);
    auto it = its.first;
    while (it != its.second) {};
  
    return 0;
}

Please provide a standalone code sample with which the issue can be reproduced, specify which compiler you use and what error you get.
