Inconsistent constVariablePointer. Part 3

[Nikita Leontiev]

cppcheck 2.20.0 doesn't generate constVariablePointer for the following code:

#include <string>

using std::wstring;

class Object
{
private:
    wstring m_str;
public:
    Object() : m_str(L"str") {}
    const wstring& get_str() const { return m_str; }
};

Object* get_object()
{
    static Object obj;
    return &obj;
}

void func(const wchar_t*) {}

int main()
{
    Object* obj = get_object();
    func(obj->get_str().c_str());
    return 0;
}

obj can be pointer to const.
constVariablePointer is generated with --std=c++03 arg:

test\main.cpp:24:10: style: Variable 'obj' can be declared as pointer to const [constVariablePointer]
 Object* obj = get_object();
         ^

Without "using std::wstring;", constVariablePointer is not generated:

class Object
{
private:
    std::wstring m_str;
public:
    ...
    const std::wstring& get_str() const { return m_str; }
};

After replacing std::wstring with std::string, constVariablePointer is generated regardless of --std=c++03.
