title: Limit on size of stl stack object
body: <p>Is there any limit on the size of a <code>std::stack</code>?</p>
  
  <p>I am using a <code>std::stack&lt;std::pair&lt;int,std::string&gt;&gt;</code> as my stack, and when the number of entries exceeds roughly 1 million, I am getting a runtime error.</p>
  
  <p>Is this due to a restriction on the size of <code>std::stack</code>?</p>
