Question

My Test class has a const static member of a subtype. I usually define this const static member as follows.

class Test 
{
public:
    class Dummy {};

private:
    static Dummy const dummy;

};

Test::Dummy const Test::dummy;             // ERROR HERE

int main() 
{
    return 0;
}

When compiling this source with gcc-4.6, it gives no error and compiles correctly.

When compiling this same source with gcc-4.4, it gives the following error:
error: uninitialized const ‘Test::dummy’
on the marked line.

• Is there another way to define this static const member variable?
• Is this a limitation of gcc-4.4?
• Is there a workaround?

Say:

Test::Dummy const Test::dummy = { };
