Why list objects with static members not accessible during debug

nyakacs

Hello,

I have been struggling to debug a large code using std::list extensively. It seems that objects in a list are not accessible in the debugger using Creator if they contain a static member. I tried various version including the latest 4.3.0.

I managed to distil the problem to the below example. As shown in the attached image, objects of Test1 are labelled <not accessible>, whilst Test2 are fine inside the list. Objects outside of the list are accessible independently from having a static member or not.

Any help would be greatly appreciated.

#include <iostream>
#include <list>
 
class Test1
{
public:
    static const int NOPOS=-1;
    int a;
};
 
class Test2
{
public:
    const int NOPOS=-1;
    int a;
};
 
int main()
{
    std::list<Test1> list1;
    Test1 t11;
    list1.push_back(t11);
    Test1 t12;
    list1.push_back(t12);
 
    std::list<Test2> list2;
    Test2 t21;
    list2.push_back(t21);
    Test2 t22;
    list2.push_back(t22);
 
    return 0;

Hi,

Sounds like you may have found something.

Which version of Qt are you running ? On what OS ?

Hi,

It is the latest creator 4.3.0. I tried it with Qt5.3.1 and 5.9.1 so I assume all version in between at least. The OS is Win10.

Did you also check with Qt Creator 4.3.1

I have now. It was not out when I did the original test. Anyway with Creator 4.3.1 it seems to be OK independently from the compiler or Qt version. I guess this solves it. Thanks for pointing out.
