                    have debug_expr_decl in split_function, at
                    ipa-split.c:1397 since r12-4920-g1ece90ffa9ce63b4
           Product: gcc

  Target Milestone: ---

The following was isolated from Godot game engine:

$ cat canvas.ii
void pthread_mutex_unlock(int *);
int __gthread_mutex_unlock___mutex, unlock___trans_tmp_1;
struct Object {
  void _change_notify() {}
  bool _is_queued_for_deletion;
};
struct ClassDB {
  template <class N, class M> static int bind_method(N, M);
};
struct CanvasItemMaterial : Object {
  bool particles_animation;
  void set_particles_animation(bool);
};
void CanvasItemMaterial::set_particles_animation(bool p_particles_anim) {
  particles_animation = p_particles_anim;
  if (unlock___trans_tmp_1)
    pthread_mutex_unlock(&__gthread_mutex_unlock___mutex);
  _change_notify();
}
void CanvasItemMaterial_bind_methods() {
  ClassDB::bind_method("", &CanvasItemMaterial::set_particles_animation);
}

$ g++ canvas.ii -O2 -g
during GIMPLE pass: fnsplit
canvas.ii: In member function ‘void
CanvasItemMaterial::set_particles_animation(bool)’:
canvas.ii:22:1: internal compiler error: tree check: expected ssa_name, have
