Debugging with gdb does not show static variables in member functions

class SomeClass
{
public:
    SomeClass()
    {
        static int a = 4;
        ++a;
    }

    void someFunction()
    {
        static int b = 4;
        ++b;
    }
};

int main(int argc, char *argv[])
{
    SomeClass someObject;
    someObject.someFunction();
    return 0;
}
