--- Comment #2 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
Reduced test-case:

$ cat pr107282.ii
template <typename _Visitor, typename _Variants>
void visit(_Visitor, _Variants);
template <class... Ts> struct overloaded : Ts... {
  using Ts::operator()...;
};
template <class... Ts> overloaded(Ts...) -> overloaded<Ts...>;
template <class> int copyLifeState(int value) {
  visit(overloaded{[] { overloaded{[] {}}; }}, value);
  return 0;
}

int
main() { int value =3D copyLifeState<int>(value); }

Maybe started with r11-6855-g4804de453e7f5f90.=
