title: How to get the full call stack from Valgrind?
body: <p>I run <a href="http://valgrind.org/" rel="noreferrer">Valgrind</a> with the following parameters:</p>
  
  <pre><code>--leak-check=full --show-reachable=yes --leak-resolution=high --num-callers=100 --trace-children=yes
  </code></pre>
  
  <p>In memory leaks log, I see some error messages with full stack trace up to main, but some messages look like following:</p>
  
  <pre><code>==3956== 1,999,140 (68,796 direct, 1,930,344 indirect) bytes in 5,733 blocks are definitely lost in loss record 8,842 of 8,845
  ==3956==    at 0x4022AB8: malloc (vg_replace_malloc.c:207)
  ==3956== 
  </code></pre>
  
  <p>How can I get the full stack trace for these errors?</p>
