            Bug ID: 117257
           Summary: Problem of std::complex<double> and maybe GCC accepts
                    invalid
           Product: gcc
           Version: 14.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: qurong at ios dot ac.cn
  Target Milestone: ---

For this program:


```
#include <complex>

int main()
{
    std::complex<double> c({1.0, 0.0});
    return 0;
}
```

This causes an error in clang, but GCC didn't report the error.
