title: How can I step through nested function calls in GDB?
body: <p>Sometimes I want to debug functions like this:</p>
  
  <pre><code>my_func1(my_func2(my_func3(val)));
  </code></pre>
  
  <p>Is there a way I can step through this nested call in GDB?</p>
  
  <p>I want to step through my_func3, then my_func2, then my_func1, etc.</p>
