--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Slightly different testcase but the same issue:
```

#include <cstddef>
template <auto F = [] <auto G = [] {
    struct S {
        int out;
    };
    int offset = offsetof(S, out);
}> () {}>
void f() { F(); }

int main() { f(); }
```

But this is the same issue as PR 123550  really.
