title: "Serious error when reading debug info" - suppress? ignore? fix?
body: <p>I'm using valgrind to try and locate the cause of a violating memory access in a C-cum-C++ program. Even with this access averted (i.e. when everything runs fine), valgrind tells me:</p>

  <p>What should I do about these warnings? Should I...</p>
  
  <ul>
  <li>Fix them somehow? It's in the system libraries, not in my code; is it even possible to do something about them?</li>
  <li>Suppress them somehow (but without suppressing any bona-fide error message)?</li>
  <li>Ignore them - if I can neither fix nor suppress?</li>
  </ul>
