When there is a using type alias for a struct inside a namespace, the code model gets confused and thinks that subsequent functions are in the namespace named as the alias:

#include "myclass.h"

namespace ns {

using StructType = struct {
    int a;
    char b;
};

MyClass::MyClass()
{
}

void MyClass::Function()
{
}

} //ns

This results in the following model:

Consequently, this causes the Function() to be unreachable when ctrl+LMB cliked in the header.

When I remove the using StructType it's ok again.

Whole project attached.
