Follow-up Comment #4:

Rik, thank you for going into this.  This surprised me indeed, too.
 

// compile with:
//
//  (clan)g++ -std=c++11 -Wall -Wextra -pedantic

#include <iostream>
#include <memory>
#include <vector>

std::unique_ptr<std::vector<int>> global_stuff;

std::vector<int> do_something () {
  std::vector<int> retval;

  return *global_stuff;

  return retval;
}

int main () {
  global_stuff = std::unique_ptr<std::vector<int>> (new std::vector<int> ({1,
2, 3}));

  std::vector<int> val = do_something ();

  for (auto const& v : val) {
    std::cout << v << ' ' << std::endl;
  }

  return 0;
}


Entirely undetected my garbage in both GCC and clang?!

Anyways, I fixed this
https://hg.savannah.gnu.org/hgweb/octave/rev/bc521cd24922

It might take more time to get into the rest, where to fix this
appropriately.
