title: how to force valgrind to show only memory leaks?
body: <p>I'd like to know how to force Valgrind tool to show only memory leaks!</p>
  
  <p>with <code>--leak-check=full</code> or <code>--leak-check=full</code> it shows memory leaks (which is good) but also uninitialization problems and/or conditional jump taking problems </p>
  
  <p>thanks!</p>
