gcc/cp/coroutines.cc:2654:3: warning: Assignment of function parameter
 has no effect outside the function. Did you forget dereferencing it?

Source code is

  /* As far as it's necessary, we've walked the subtrees of the call
     expr.  */
  do_subtree = 0;
  return NULL_TREE;
}

Following on from code in the same routine, maybe better code might be

  /* As far as it's necessary, we've walked the subtrees of the call
     expr.  */
  *do_subtree = 0;
  return NULL_TREE;
}
