--- Comment #11 from Patrick Palka <ppalka at gcc dot gnu.org> ---
FWIW -ffold-simple-inline is sufficient to trigger the ICE, so this has
something to do with cp_fold's folding of std::move.  More reduced:

$ cat 107267.C
namespace std {
  template<typename _Tp> _Tp &&move(_Tp &&);
}

struct FindResult {
  FindResult();
  int result;
};

FindResult pop_ret =3D std::move(FindResult());

$ g++ -ffold-simple-inlines 107267.C
107267.C:10:44: internal compiler error: in cp_gimplify_init_expr, at
cp/cp-gimplify.cc:253
   10 | FindResult pop_ret =3D std::move(FindResult());
