  Since we are redirecting the gdb interrupt messages to the file `<path-you-run-gdb>/profile.txt` (see the gdb script,) we can now parse the log and visualize it.

  #### Get the statistic of the function call hierarchy
  To get a more detail view of how the entire function call stack looks like and how many time the function is called with the exact same call stack, we can add another option `--full-trace` to the script and it will generate a `*.json` file for the complete call stack trace.
