            Bug ID: 109459
           Summary: static_assert with operator""s causes internal
                    compiler error
           Product: gcc
           Version: 12.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: stevenxia990430 at gmail dot com
  Target Milestone: ---

The following program reports an internal compiler error: Segmentation fault

To quickly reproduce: https://gcc.godbolt.org/z/T6E8Tb7ff
```
#include <string_view>
#include <iostream>
int main()
{
    using namespace std::literals;
    int x =3D 0;
    static_assert(std::is_void_v<std::decay_t<decltype(x)>>, "Cannot process
pair."s);

    return 0;
}
```

Removing the operator""s removes the internal compiler error.=
