title: gdb no symbol table loaded for core file
body: <p>There was a core dump produced at the customer end for my application and while looking at the backtrace I don't have the symbols loaded...</p>

  <p>One think I want to mention in here is that the application being used is build with -g option.</p>
  
  <p>To me it seems that the required libraries are not being loaded. I tried to load the libraries manually using the "symbol-file", but this doesn't help.</p>
  
  <p>What could be the possible issue?</p>
