--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
```
struct GLS {
int a;
};
auto GL2 = []();
constexpr GLS (*fp3)() = GL2;
static_assert(fp3().a == '3', "");
```
Started in GCC 7.1.0 (when adding -std=c++17).
>Starts to baliling out since gcc-11
That is just when the default C++ version was increased to 17.
