            Bug ID: 101344
           Summary: braced-init-list not supported in an aggregate
                    deduction
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

Please consider the program as follows. GCC correctly initializes struct A,=
 but
in more simple case of struct B it fails:

```
template<typename T, int N>
struct A { T t[N]; };

template<typename T>
struct B { T t[2]; };

int main()
{
   A a{{1, 2}}; // ok in gcc
   B b{{1, 2}}; // error in gcc (ok in other compilers, e.g. msvc)
   return a.t[0];
}
```

I believe, struct B initialization shall work here same way.=
