title: Segmentation fault while trying to print size of a vector inside a structure
body: <p>This piece of code gives me an error</p>
  
  <pre><code>struct state{
      int time_taken;
      vector&lt;int&gt;time_live;
      string loc_name;
      vector&lt;int&gt;loc;
  };
  
  
  for(int u=0;u&lt;(A[start].loc.size());u++)
  {
    l=A[start].loc[1];
    if(A[l].time_taken &lt; min_time)
    { 
      min_time=A[l].time_taken;
      finish = l;
    }
  }
  </code></pre>
  
  <p>This gives a segmentational fault . </p>
