            Bug ID: 108460
           Summary: -Wmissing-braces with ctad
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tim at klingt dot org
  Target Milestone: ---

consider this snippet, that uses class template argument deduction for arrays

```
#include <array>

std::array a {"a", "b", "c"}; // ctad, but emits -Wmissing-braces
std::array b {{"a", "b", "c"}}; // does not build
```

this makes me wonder if `-Wmissing-braces` should fire in case `a`?
