title: How to suppress file warnings in GDB?
body: <p>When I <em>debug</em> a C-program with <strong>gdb</strong> I often run into warnings like these:</p>
  
  <pre><code>66  ../sysdeps/x86_64/strlen.S: File or directory not found.
  (gdb) step
  67  in ../sysdeps/x86_64/strlen.S
  (gdb) s
  68  in ../sysdeps/x86_64/strlen.S
  (gdb) s
  69  in ../sysdeps/x86_64/strlen.S
  (gdb) s
  70  in ../sysdeps/x86_64/strlen.S
  ...
  </code></pre>
  
  <p>This keeps going on for a while, until the file is found (I guess). Later the program continues but gdb runs into another unknown file and so on...</p>
  
  <p>What's wrong? How can I get rid of these errors/warning?</p>
