Since this is C++ you should not use NULL anyway. so the above code
should be
  if (m_future.getEdges().second)

(See the book by Bjarne Stroustrup, the creator of C++, "The C++
Programming Language", published in year 2000: quote from page 88:
"In C, it has been popular to define a macro NULL to represent the zero
pointer. Because of C++'s tighter type checking, the use of plain 0,
rather than any suggested NULL macro, leads to fewer problems." At page
433, he calls the NULL macro "infamous".)
