            Bug ID: 114053
           Summary: GCC accepts initialization of array with another
                    static data member array in member initializer list
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jlame646 at gmail dot com
  Target Milestone: ---

The following program is accepted by gcc but rejected by both clang and msvc:

```
struct I {
    const bool b;

};
struct O {

    I a[2];  

    static I const data[2];
    O() : a(data){}
} ; 

I const O::data[2] = {true, false};
```

Is this a bug or some non-standard extension?
